6. What is a virtual image? Give one situation where a virtual image is formed.
Ans: Virtual image: When light rays seem to originate at a spot but do not actually intersect, a virtual image is created. It is visible to human eyes. As a result, rear-view mirrors create virtual images.
The situations where a virtual image is formed:
It is formed when reflected rays appear to meet.
Such images cannot be obtained on the screen.
Virtual images are always formed in the plane mirror and convex mirror.

9. Which type of lens always forms a real image?
Ans: Neither concave nor convex lens always form a real image. A convex lens forms both real and virtual images. A concave lens forms virtual, erect and diminished images.
10. Which type of lens always forms a virtual image?
Ans: The type of lens which always forms a virtual image is:
A concave lens always forms a virtual image.
After the rays are refracted, they never converge and so there will be no real image.

Concave lens
Concave mirror
Convex lens
Plane mirror
Ans: (b) Concave mirror.

12.David is observing his image in a plane mirror. The distance between the mirror and his image is 4 m. if he moves 1m towards the mirror, then the distance between David and his image will be
3 m
5 m
6 m
8 m
Ans: (c) 6 m.
In the above image,
The distance between the mirror and the object is equal to the distance between the mirror and the image.
The distance between mirror and David image is 4m
When he moves 1m towards the mirror, then the distance is reduced as,
Distance between the mirror and the object is 4-1=3m.
Therefore, the distance between David and his image is 3+3=6m.
13. The rear-view mirror of a car is a plane mirror. A driver is reversing his car at a speed of 2 m/s. The driver sees in his rear-view mirror the image of a truck parked behind the car. The speed at which the image of the truck appears to approach the driver will be
1 m/s
2 m/s
4 m/s
8 m/s.
Ans: (c) 4 m/s.
In a plane mirror, the object and its image always remain at the same distance from the mirror. So, when the car reverses at a speed of 2m/s, then the image will also appear to move towards the driver.
Therefore, the speed at which the image of the truck appears to approach the driver will be 2+2=4m/s.
NCERT Class 7 Science Chapter 11 Light - Quick Overview of Detailed Structure of Topics
Important Points Covered in Class 7 Science Light
Light is a form of energy that enables us to see objects when it gets reflected from them. Light can be detected through our eyes.
Light travels along a straight line.
There are two types of images i.e. real images and virtual images.
The process of changing the path of light through a mirror or shiny object is called the reflection of light.
There are two types of spherical mirrors i.e. convex mirrors and concave mirrors.
Lenses are defined as transparent pieces of glass. Lenses are bounded by two spherical surfaces.
When white light passes through a glass prism then white light gets split into seven colors. This phenomenon of splitting white light is called dispersion of light.

FAQs on NCERT Solutions for Class 7 Science Chapter 11 Light
1. What are the main concepts explained in the NCERT Solutions for Class 7 Science Chapter 11 Light?
The NCERT Solutions for Class 7 Science Chapter 11 Light cover key concepts including properties of light, reflection, refraction, types of mirrors and lenses, image formation, differences between real and virtual images, and phenomena such as dispersion and rainbow formation—all aligned as per CBSE 2025–26 syllabus.
2. How does the NCERT Solution describe a virtual image in the context of Class 7 Science Light Chapter?
A virtual image is an image in which the reflected or refracted rays appear to meet but do not actually converge. Virtual images cannot be displayed on a screen. Plane mirrors and convex mirrors always produce virtual, erect images.
3. What are the differences between convex and concave lenses, according to Class 7 Science Chapter 11 NCERT Solutions?
- Convex lens: Thicker in the middle, thinner at edges; can form both real and virtual images; converges light rays.
- Concave lens: Thinner in the middle, thicker at edges; always forms virtual, erect, and diminished images; diverges light rays.
4. Why can't a real image be formed by a concave lens, as per the solutions for Class 7 Science Chapter 11?
A concave lens always produces diverging rays, so the refracted rays never intersect on the same side of the lens as the object. Thus, concave lenses cannot form a real image; only virtual, erect, and diminished images are possible.
5. What advantages do Vedantu's NCERT Solutions provide for mastering Light in Class 7 Science?
Vedantu’s NCERT Solutions offer stepwise explanations, CBSE-patterned answers, clarifications for tricky concepts like reflection/refraction, and multiple question formats. Visuals and real-life examples make Learning Light more relatable, promoting higher accuracy in exams as per 2025–26 CBSE guidelines.
6. What is meant by the reflection of light according to the NCERT Solutions for Class 7 Science Chapter 11?
Reflection of light is the process where light bounces off a polished or shiny surface (like a mirror), changing its direction. The reflected rays follow the law of reflection, where the angle of incidence equals the angle of reflection.
7. Which main principles of light are elaborated in Chapter 11 of the Class 7 NCERT Solutions?
The solutions discuss these main principles: light travels in a straight line, reflection and refraction phenomena, formation and type of images, laterally inversion, spherical mirrors and lenses, dispersion of white light through a prism, and daily-life applications of these concepts.
8. How do NCERT Solutions for Class 7 Science Chapter 11 aid in understanding image formation by mirrors and lenses?
The solutions detail how plane and spherical mirrors, as well as convex and concave lenses, form images based on light’s behaviour with surfaces. They provide solved problems, diagrams, and practical scenarios for clarity on image position, size, and orientation.
9. What are the core properties of the image formed by a plane mirror, as per the NCERT Class 7 Science Solutions?
- The image is virtual, erect, and of the same size as the object.
- The image distance behind the mirror equals the object’s distance in front.
- The image is laterally inverted (left-right reversal).
10. How does the NCERT Solution for Class 7 Science Chapter 11 explain the concept of lateral inversion?
Lateral inversion is the phenomenon where left and right sides of an object appear reversed in the plane mirror image. This concept helps explain why text appears flipped in a mirror.
11. What if a student mistakes a convex lens for a concave lens? How might this impact their understanding of light in Class 7 Science?
If a convex lens is mistaken for a concave lens, students may wrongly believe that the lens always diverges light or forms only virtual images. This misconception hinders understanding image formation principles and can affect answers to higher-order CBSE questions involving ray diagrams or real-life lens applications.
12. In Class 7 Science Chapter 11, why does a concave mirror form both real and virtual images, but a convex mirror does not?
A concave mirror's inward curve allows reflected rays to actually meet (real image) or appear to meet (virtual image) based on object position. A convex mirror, being outwardly curved, always causes rays to diverge, so the image is invariably virtual, diminished, and located behind the mirror.
13. Why is it important for CBSE Class 7 students to distinguish between real and virtual images in NCERT Solutions for Light?
Distinguishing between real and virtual images is crucial because exam questions often ask about their formation, properties, and applications (e.g., mirrors in vehicles versus magnifying glasses). A clear understanding ensures accurate answers as required by recent CBSE marking schemes.
14. What common student mistakes does the Light Chapter’s NCERT Solution help clarify?
Vedantu’s NCERT Solutions address frequent errors such as misidentifying image types, confusing lenses and mirrors, and incorrectly applying the law of reflection or refraction. Stepwise worked examples and conceptual summaries help prevent these mistakes.
15. How can Class 7 Science Chapter 11 Solutions help students solve numerical problems involving light?
The solutions provide stepwise mathematical reasoning for ray diagrams, image distances, lateral inversion effects, and speed calculations (e.g., mirror and object movement). This builds problem-solving skills needed for CBSE-based short and long-form questions.
