FAQs on Light and Shadow - 1 Class 6 Worksheet Science

1. What is light and shadow?
Ans. Light is a form of energy that enables us to see objects, while shadows are dark areas created when an object blocks light. Light travels in straight lines and can be absorbed, reflected, or transmitted by different objects.
2. How is light produced?
Ans. Light can be produced through various sources such as the sun, fire, light bulbs, and even certain chemical reactions. These sources emit energy in the form of electromagnetic waves, which we perceive as light.
3. Why do shadows change in size and shape?
Ans. Shadows change in size and shape because they are formed when an object blocks light. The size and shape of the shadow depend on the distance between the object, the light source, and the surface on which the shadow is cast. As these factors change, the shadow will also change accordingly.
4. What is the difference between transparent, translucent, and opaque objects?
Ans. Transparent objects allow light to pass through them, making objects behind them visible. Translucent objects only allow some light to pass through them, resulting in a blurry or diffused image. Opaque objects do not allow any light to pass through them, creating a solid shadow.
5. 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, such as outer space, as well as transparent mediums like air, water, and glass. When light encounters a different medium, it may change direction or speed, a phenomenon known as refraction.
