Class 3 EVS Light and Shadow Question and Answers:
1. What is the main source of natural light on Earth?
The Sun is the main source of natural light on Earth.
2. What are luminous objects?
Luminous objects are those that emit their own light, such as the Sun and stars.
3. How is shadow formed?
A shadow is formed when an opaque object blocks the path of light.
4. Why is the Moon not a luminous object?
The Moon does not produce its own light; it reflects light from the Sun.
5. What happens when light hits a mirror?
Light reflects off the mirror in one direction, making it a good reflector.
6. What is the difference between transparent and translucent materials?
Transparent materials allow all light to pass through, while translucent materials allow only some light to pass through.
7. What is lateral inversion?
Lateral inversion is the reversal of an image as seen in a mirror.
8. Why can we not see objects in complete darkness?
We cannot see objects in complete darkness because there is no light to reflect off the objects and enter our eyes.
9. What type of material is glass?
Glass is a transparent material.
10. What is the speed of light?
The speed of light is approximately 300,000 km per second.
11. Why are mirrors polished surfaces?
Polished surfaces allow mirrors to reflect light in a single direction .
12. How does the distance of an object from a light source affect its shadow?
When the object is closer to the light source, the shadow becomes larger; when it is farther, the shadow becomes smaller.
13. Why do shadows appear long in the morning and evening?
Shadows appear long in the morning and evening because the Sun is low in the sky.
14. What is the difference between natural and artificial light sources?
Natural light sources include the Sun and stars, while artificial light sources include bulbs and candles.
15. Why do we see colors?
We see colors because light reflects off objects and enters our eyes, with different wavelengths producing different colors.
