NCERT Solutions For Science Class 10 - Light Reflection and Refraction
Chapter 10 Class 10 Science is mostly about reflection and refraction of light. The main topics included consist of spherical mirrors, magnification, reflection, refraction and power of a lens. To provide simplification, Light Reflection and Refraction Class 10 Solutions include various diagrams, logical problems and detailed content in simple words.
The topic Reflection of Light Class 10 refers to light waves bouncing off the surface of objects that do not have the capability of absorbing energy produced by radiation. A surface of a pool, for example, will display clarity of surrounding objects when still. Whereas, all the rays would be scattered once a rock is thrown inside it preventing systematic reflection of light.
Refraction of light Class 10, on the other hand, refers to the bending of light waves when it travels from a faster to a slower medium. Images formed by lenses and our eyes exist due to this process.
All the aforementioned topics are thoroughly explained under Chapter 10 Science Class 10 solutions by teachers having expertise in the subject. Physics subject requires students to have a good grip on the basic understanding of the concepts. NCERT Solutions for Class 10 Science Chapter 10 provides an easy understanding of the various topics that can help students to secure good marks.

FAQs (Frequently Asked Questions)
1. Why do Vehicles have Convex-Shaped Rear View Mirrors?
A convex mirror is used as a rearview mirror in vehicles as it gives a more extensive field of view, which causes the driver to see the vast majority of the traffic behind him. Convex mirrors consistently structure an erect, virtual and decreased picture of the things set in front of it.
2. What is Meant by 1 Dioptre of Power of Lens?
Dioptre is the SI unit of intensity of focal point and is denoted by the letter D. 1 dioptre can be characterized as the intensity of a focal point/power of a lens of central length 1 metre.

5. What do you understand about the refraction of light? Also, state the laws of refraction of light.
Refraction of light is the process in which the direction and speeds of light change when moving from one medium to another.
Laws of Refraction of Light:
The normal, the incident ray and the refracted ray all lie in the same plane.
The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant for the light of a given colour and for the given pair of media. This law is known as Snell's law.
6. What is meant by the term magnification of spherical mirrors?
The magnification of spherical mirrors is defined as the ratio of the height of the image to the height of the object. It is denoted by ‘m’. This magnification is also described in terms of object and image distance. The negative ratio of the image distance to the object distance is known as magnification. The negative magnification shows that images are real. The positive sign in the value of magnification tells that the image is virtual.
7. Write a short note on the power of a lens.
The power of a lens is defined as the ability of the lens to diverge or converge the light rays depending on the focal length. The short focal length of the concave lens causes higher divergence than the one with a longer focal length. The power of the lens is also defined as the reciprocal of its focal length. It is denoted by “P”. The SI unit of power of the lens is ‘dioptre’. 1 dioptre is described as the power of a lens whose focal length is 1 metre.
