FAQs on Light Class 7 Worksheet Science Chapter 13

1. What is light?
Ans. Light is a form of electromagnetic radiation that is visible to the human eye. It is a type of energy that travels in waves and can be perceived as colors by our eyes.
2. How does light travel?
Ans. Light travels in straight lines called rays. It travels at a speed of approximately 299,792 kilometers per second in a vacuum. When light encounters a different medium, such as air or water, it can change direction due to refraction.
3. What are the primary sources of light?
Ans. The primary sources of light are natural sources, such as the Sun, stars, and fire, and artificial sources, including light bulbs, lamps, and LED lights. These sources emit light energy that can be used for various purposes.
4. How does light interact with objects?
Ans. When light interacts with objects, it can be reflected, absorbed, or transmitted. Reflection occurs when light bounces off the surface of an object. Absorption happens when light is absorbed by the object, converting it into other forms of energy. Transmission occurs when light passes through an object without being absorbed or reflected.
5. How does light enable us to see objects?
Ans. Our eyes are sensitive to light, and when light reflects off objects and enters our eyes, it stimulates specialized cells called photoreceptors. These photoreceptors convert the light into electrical signals that are sent to our brain, allowing us to see and perceive the objects around us.
