3. Can you think of creating a shape that would give a circular shadow if held in one way and a rectangular shadow if held in another way?
Ans: Yes. If the curved surface of the cylinder is placed perpendicular to the path of the light, the shape of the shadow obtained is a rectangle.
4. In a completely dark room, if you hold up a mirror in front of you, will you see the reflection of yourself in the mirror?
Ans: No, because light is required for reflection to generate an image, one cannot see one's reflection in a fully dark environment.

Chapter 11 – Light, Shadow & Reflection
Light helps in seeing various objects around us. It is a form of energy. When an object receives light, some of the illuminations get reflected. It is because of the reflection that we see things around us. We can’t see things in the dark, not because there isn’t enough light, but because there isn’t any reflection. NCERT solutions Class 6 Science Chapter 11 provides you with a thorough insight into the chapter of light, shadow and reflection.
What are the Sources of Light?
There are two sources of light. These are:
Luminous: It is a body that emits light on its own. It can be found naturally and artificially. Few examples include - The sun, electric bulb, etc.
Non - Luminous: It is a body that is unable to emit light on its own. These bodies only reflect for which we can see. Few examples include - Moon, mirrors etc.
Note*: We can see our face in the mirror only because it reflects. If we hold a mirror in a dark room it is impossible to see objects through it.
To know more about luminous and non-luminous examples and definitions, consider following NCERT Science Class 6 Chapter 11 solutions.
Transparent, Translucent and Opaque
Transparent: If a source of light passes through any object, it is known as a transparent object. Few examples include – water, glass, etc.
Translucent: If a source of light partially through an object, it is known as a translucent object. Few examples include – butter paper, frosted glass, etc.
Opaque: If a source of light is completely blocked trying to pass through an object, it is known as opaque. Few examples include – The Earth, wood, etc.
NCERT Science Book Class 6 Chapter 11 solutions provide a detailed study on the concepts of transparent, translucent and opaque.
Formation of Shadows
If an opaque object blocks a source of light, it creates a shadow. The shadow is created by the opposite side of the object (the darker side). The distance between a source of light and an opaque object signifies the size of the shadow. The angle of light also plays a major role. NCERT Solutions of Class 6 Science Chapter 11 have curated interesting and attractive lessons when it comes to the lessons of shadows. Students from Class 6 can achieve additional ideas and concepts from the downloadable sources.
Various Sizes of Shadows
When the source of light comes closer to the opaque object, the size of the shadow tends to grow bigger. On the flip side, the size reduces when the source of light moves away from the object.
The shadow created by an opaque object can only be seen when the shadow falls on a screen. This includes anything from, ground, walls of a room, or any surface that acts as a screen.
Sometimes the shadow provides a lot of information about the object.
Shadows are always black and cannot be changed by the color of the opaque object.
Propagation of Light
Light is known to travel in a straight line, and this is called rectilinear propagation of light. When this concept is represented through various notes like in the NCERT solution for Class 6 Science Chapter 11, two important terms are used to serve the purpose. These include Beam of Light and Ray of Light.
Beam of Light: When a bunch of rays moves towards a specific direction.
Ray of Light: It is the path through which light travels to a specific direction.
Reflection of Surfaces
It is said that light reflects when it bounces off a surface. Now, the nature of reflection depends on the type of surface. When a source of light falls on an irregular surface, the parallel beam of light reflects in different directions based on the angles on the surface. It is known as diffused reflection.
If the same happens on a smooth surface, the parallel beam of light reflects uniformly to a single direction depending on the angle of light. This is known as an image. A perfect example includes when we see ourselves through a mirror.

FAQs on NCERT Solutions for Class 6 Science Chapter 11 - Light, Shadows And Reflections
1. What do you Understand by Light Shadow and Reflection?
The time light falls on any object, some amount of light starts to reflect. This reflected amount of light comes back to human eyes, and that’s how we see any object. Sun is a prime example of a luminous object (produces light).
2. Which Property of Light is Responsible for a Shadow?
If there is a barrier in the way of light, the light generally bounces back. Shadow is the reason for that shielded place because light does not reach that place. The reason we see the shadow is light is all over other than the shielded area.
3. Where can I get the accurate NCERT Solutions for Chapter 11 of Class 6 Science for free?

5. Write the difference between shadow and image according to Chapter 11 of Class 6 Science.
An image is formed by the intersection of reflected rays whereas when light does not reach behind the object, the shadow is formed. When reflected rays reach the observer's eyes, the image can be seen whereas, for the shadow, light does not enter the observer’s eye. Image can either be straight or inverted and provides us with information such as colour, structure etc. Shadow is never inverted and does not provide such information as colour, structure.
6. What are transparent, translucent and opaque objects according to Chapter 11 of Class 6 Science? Explain with examples.
Transparent objects are those objects through which light can pass easily and we are able to see clearly through them. For example- Glass, water etc.
Translucent objects are those objects through which light passes partially and we can see through it but not clearly. For example- tracing paper, butter paper etc.
Opaque objects are those objects through which light cannot pass at all and through that object, we cannot see anything at all and only these objects can make shadows. For example -wood, plastic box, blackboard, etc.
7. What is an eclipse? What are the two types of eclipses? Write the answer in accordance with Chapter 11 of Class 6 Science.
Eclipse is known as the formation of shadows by celestial bodies on one another. There are two types of eclipse - Solar and Lunar eclipse.
A solar eclipse occurs when the shadow of the moon falls on the earth when the moon comes in between the sun and the earth.
A lunar eclipse occurs when the shadow of the earth falls on the moon when the earth comes in between the sun and the moon.
