# Light and Shadow - 1 Class 2 Worksheet Science

### Q1: Tick (✓) the correct choice

(i) This does not use electricity to give us light.

(b) Tube light
(c) Bulb

Ans: (a)
The candle symbolizes light in the darkness of life, especially individual life.

(ii) The size of our shadow during the daytime
(a) remains the same
(b) keeps changing
(c) none of these

Ans: (b)
These changes are caused by the position of the light source. When we are outside on a sunny day, we can see how our shadows change throughout the day. The Sun's position in the sky affects the length of the shadow. When the Sun is low on the horizon, the shadows are long.

(iii) The shadow of a pole will be the shortest
(a) in the morning
(b) in the evening
(c) at noon

Ans: (c)
The shadow cast by a pole under the sun will be the shortest at 12 noon.

The moon shines because of the light of the sun.

### Q3: True & False

(i) At noon time, the shadow of an object is the shortest.
Ans:
True
As the Sun moves, light falls on the object at an angle. The bigger angle, the longer the shadow. At noon, the Sun is directly overhead. This makes the smallest angle with the objects and so creates the shortest shadows.

(ii) The moon does not have its own light.
Ans:
True
The moon shines because its surface reflects light from the sun.

(iii) We are not able to see properly in the absence of light.
Ans:
True
We can see things when rays of light coming from any object reach our eyes. So, we cannot see in the dark because of the absence of light.

### Q4: Match the following

Ans:

(i) On what factor does the size of the shadow of an object depend?
Ans:
The size and nature of shadow depends on the source of light and the position of the object with respect to the source and the screen.

(ii) Write any three sources of light other than that you have read here.
Natural sources of light include the sun, stars, fire, and electricity in storms. There are even some animals and plants that can create their own light, such as fireflies, jellyfish, and mushrooms.

## FAQs on Light and Shadow - 1 Class 2 Worksheet Science

 1. What is light?
Ans. Light is a form of energy that allows us to see things. It travels in straight lines and can be reflected, refracted, or absorbed.
 2. How does light travel?
Ans. Light travels in straight lines at a speed of approximately 299,792 kilometers per second. It can travel through a vacuum or through transparent materials such as air, water, or glass.
 3. What causes shadows to form?
Ans. Shadows are formed when an object blocks the path of light. As light cannot pass through the object, it creates an area behind the object where light cannot reach, resulting in a shadow.
 4. How does the size of a shadow change?
Ans. The size of a shadow can change depending on the distance between the object and the light source. When the object is closer to the light source, the shadow appears larger. Conversely, when the object is farther away, the shadow appears smaller.
 5. Can shadows have different shapes?
Ans. Yes, shadows can have different shapes depending on the shape of the object blocking the light. Objects with irregular shapes may create distorted or elongated shadows, while objects with regular shapes may create well-defined and symmetrical shadows.
