FAQs on What is Reflection of Light? Video Lecture - Science Olympiad Class 7

1. What is reflection of light?
Ans. Reflection of light is the phenomenon by which light bounces back when it strikes a surface. It occurs when light waves encounter a boundary between two different mediums, causing a change in direction.
2. How does reflection of light occur?
Ans. Reflection of light occurs when light waves strike a surface and bounce back into the same medium from which they came. The angle of incidence, which is the angle between the incident light ray and the normal to the surface, is equal to the angle of reflection, which is the angle between the reflected light ray and the normal to the surface.
3. What are the laws of reflection?
Ans. The laws of reflection state that the angle of incidence is equal to the angle of reflection, and the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie on the same plane. These laws apply to all types of surfaces, whether they are smooth or rough.
4. How does reflection of light help us see objects?
Ans. Reflection of light plays a crucial role in our ability to see objects. When light falls on an object, it reflects off its surface and enters our eyes. Our eyes receive this reflected light and transmit the information to our brain, which processes it and enables us to see the object.
5. Can reflection of light occur on all surfaces?
Ans. No, reflection of light cannot occur on all surfaces. It primarily occurs on smooth and shiny surfaces, such as mirrors, glass, and polished metals. These surfaces reflect light in a regular and predictable manner, allowing clear reflection. However, on rough and opaque surfaces, light is scattered in different directions, resulting in diffused reflection rather than clear reflection.
