Chapter 11 – Light, Shadow & Reflection


NCERT Solutions for Class 6 Science Chapters

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 act as a screen.

  • Sometimes the shadow provides a lot of information about the object.

  • Shadows are always black and cannot be changed by the colour 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 (Frequently Asked Questions)

Q1. What do you Understand by Light Shadow and Reflection?

Ans. 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).

Q2. Which Property of Light is Responsible for a Shadow?

Ans. 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.
