Reflection of light
Reflection of light is the bouncing back of light in the same medium when it falls on a smooth and polished surface. The angle of incidence is equal to the angle of reflection.
Explanation:
When light falls on a smooth and polished surface, it bounces back in the same medium. This phenomenon is called reflection of light. The surface upon which light falls is called a mirror. A mirror has a smooth and polished surface that reflects light rays and forms an image.
When a light ray falls on a mirror, it gets reflected in a particular direction. The angle of incidence is the angle between the incident ray and the normal to the surface at the point of incidence. The normal is a line drawn perpendicular to the surface at the point of incidence. The angle of reflection is the angle between the reflected ray and the normal to the surface at the point of incidence. The angle of incidence is equal to the angle of reflection.
Applications of reflection of light:
1. Mirrors are used in making periscopes, kaleidoscopes, and telescopes that use the reflection of light to form an image.
2. Reflection of light is used in headlights of vehicles to increase visibility during night driving.
3. Reflection of light is used in making solar cookers that use the sun's rays to cook food.
4. Reflection of light is used in making optical fibers that are used to transmit information through the internet.
Hence, the correct answer is option 'B' which is reflection.

When a light comes in touch with a opaque object it can't move ahead so it reflects on it's surface or bounces on the same medium or same thing.
