Ans:

2. Classify the objects or materials given below as opaque, transparent, translucent, and luminous, or non-luminous.

Air, water, a piece of rock, a sheet of aluminium, a mirror, a wooden board, a sheet of polythene, a CD, smoke, a sheet of plane glass, fog, a piece of red hot iron, an umbrella, a lighted fluorescent tube, a wall, a sheet of carbon paper, the flame of a gas burner, a sheet of cardboard, a lighted torch, a sheet of cellopane, a wire mesh, kerosene stove, sun, firefly, moon.

A.Transparent Objects: Air, water, a sheet of plane glass, a wire mesh.

• Opaque objects: A piece of rock, a wooden board, an umbrella, a sheet of aluminium, a mirror, a wall, a sheet of carbon paper, a sheet of card board.
• Translucent objects : A sheet of polythene, smoke, fog, a sheet of cellopane.
• Luminous objects: The sun, a sheet of red hot iron, a lighted fluorescent tube, a flame of a gas burner,
  a lighted torch, kerosene stove, firefly.
• Non-luminous objects : Air, water piece of rock, sheet of aluminium, sheet of polythene, wooden board, a CD, smoke, moon, etc.

3. Can you think of creating a shape that would give a circular shadow if held in one way and rectangular shadow if held in another way ?

A.Yes. If the base of cylinder is focused to light, it gives circular shadow.

If the cylinder is focused horizontally on the light, it gives a rectangular shadow.

4. In a completely dark room, if you hold up a mirror in front of you, will you see a reflection of yourself in the mirror?

A.No. It is not possible because we do not have source of light. So, a reflection of light does not take place. Hence, we can not see images in the mirror.

Class 6 Science Chapter 11 – Very Short Answer Type Questions

Q1. Whether the moon is a luminous or non-luminous body?

Ans. The moon is a non-luminous body because it cannot make its own light, it only reflects sunlight.

Q2. What is umbra?

Ans. Umbra is the fully dark part of a shadow where no light reaches.

Q3. How does a light ray travel?

Ans. A light ray always travels in a straight line.

Q4. Give one natural source of light.

Ans. The Sun is a natural source of light.

Q5. What is shadow?

Ans. A shadow is a dark area formed behind an opaque object where light cannot pass.

Q6. What is penumbra?

Ans. Penumbra is the lighter or less dark part around the main shadow.

Class 6 Science Chapter 11 – Short Answer Type Questions

Q1. State the difference between a luminous and a non-luminous body.

Ans. Luminous bodies give out their own light (like the Sun). Non-luminous bodies do not give light, they only reflect (like the Moon).

Q2. Why is the moon not considered a luminous body?

Ans. The Moon only shines by reflecting sunlight, so it is not a luminous body.

Q3. What is an incandescent body? Give an example.

Ans. An incandescent body glows when heated at very high temperature. Example: an electric bulb.

Q4. When does a shadow form?

Ans. A shadow forms when an opaque object blocks light from reaching behind it.

Q5. What are the essential conditions for the formation of a shadow?

Ans. We need three things: a light source, an opaque object, and a screen.

Q6. Define the reflection of light.

Ans. Reflection of light means light rays bouncing back after striking a shiny or smooth surface.

Q7. Write the difference between shadow and image.

Ans. A shadow is only a dark shape formed by blocking light. An image shows the object’s full details by reflection or refraction.

Q8. How will you convert a glass sheet into a translucent sheet?

Ans. By applying a thin layer of oil on glass or covering it with butter paper, it becomes translucent.

Q9. What is shadow? How does the color of an opaque object affect the color of the shadow?

Ans. A shadow is a dark region formed behind an opaque object. The color of the object does not change the shadow’s color.

Q10. Write the differences between umbra and penumbra.

Ans. Umbra is the darkest part of a shadow. Penumbra is the lighter region around the umbra.

Q11. What do we need to see a shadow?

Ans. We need a source of light, an opaque object, and a screen to see a shadow.

Q12. What do you mean by scattering of light?

Ans. Scattering of light happens when light falls on a rough surface and spreads in many directions.

NCERT Class 6 Science Chapter 11 Light, Shadow & Reflection – Topic Wise Guide

The NCERT Solutions for Class 6 Science Chapter 11 Light, Shadow and Reflection help students to explore how light behaves in our daily life. Light is a form of energy that allows us to see different objects. When light falls on an object, some part of it bounces back. This process is called reflection, and it is the main reason why we can see things around us. In darkness, we cannot see anything because no light is reflected back to our eyes. The Class 6 Science Light Shadow and Reflection question answers explain these ideas in an easy-to-understand way, making the topic very interesting.

Sources of Light

Sources of light are divided into two groups:

• Luminous objects – These give out light on their own, like the sun, stars, candle, or an electric bulb.
• Non-luminous objects – These do not make their own light but become visible only when they reflect light, like the moon, a chair, or a mirror.

If there is no light, even a mirror cannot show our face. This is why light, shadow and reflection Class 6 NCERT solutions are important to understand real-life examples.

Transparent, Translucent and Opaque Objects

Objects allow light to pass in different ways:

• Transparent: Let light pass completely. Example – water, glass.
• Translucent: Allow light partly, but not clearly. Example – butter paper, frosted glass.
• Opaque: Do not allow any light to pass. Example – wood, stone, metal.

NCERT exercises in Class 6 Science Chapter 11 explain these differences with examples and diagrams.

Formation of Shadows

When an opaque object blocks light, it forms a shadow on the opposite side. The size and shape of the shadow depend on:

• Distance between light source and object.
• The angle at which light falls.

For example, our shadow looks longer in the morning and evening, but shorter at noon. NCERT Class 6 Science solutions for Light Shadow and Reflection explain this with simple activities.

Different Sizes of Shadows

• If the light source comes closer to the object → the shadow becomes bigger.
• If the light source moves away → the shadow becomes smaller.

Shadows are always black or dark in color, no matter what is the color of the object. They are formed only when the shadow falls on a screen or surface like the ground or a wall.

Propagation of Light

Light always moves in a straight line, known as rectilinear propagation of light. Two important terms are:

• Ray of Light – The straight path of light.
• Beam of Light – A group of rays traveling together.

This idea is very useful in explaining reflection and shadow.

Reflection of Surfaces

Reflection means bouncing of light from a surface. The type of surface decides the reflection:

• On rough surfaces, light scatters in many directions (called diffused reflection).
• On smooth surfaces, light reflects evenly and forms an image, like when we look in a mirror.

Thus, reflection in Class 6 Science Chapter 11 helps students connect theory with daily examples.
