FAQs on Light, Shadow and Reflections - Introduction Video Lecture - Science Class 6

1. What is light?
Ans. Light is a form of energy that enables us to see objects around us. It is a type of electromagnetic radiation that travels in straight lines and at a very high speed.
2. What is a shadow?
Ans. A shadow is a dark area formed when an object blocks the path of light. It is formed on the opposite side of the object from the source of light. Shadows are formed due to the lack of light in that particular area.
3. How are shadows formed?
Ans. Shadows are formed when an object obstructs the path of light. When light rays from a source hit an object, they cannot pass through it. As a result, a dark area is formed on the opposite side of the object, creating a shadow.
4. What is reflection?
Ans. Reflection is the bouncing back of light from a surface. When light rays hit a smooth surface, they bounce off in a predictable manner. This phenomenon is called reflection. Examples of reflection include seeing your reflection in a mirror or the reflection of light from a shiny surface.
5. How does light travel?
Ans. Light travels in straight lines and at a very high speed. It can travel through transparent objects like air and glass, but cannot pass through opaque objects like walls. Light travels until it is absorbed, reflected, or refracted by an object in its path.
