What is the focal length of the mirror? b. What is the distance of the image formed of the ball from the vertex? c. What is the magnification of the image formed?
Applications Of Reflection Of Light
When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.
Sign Convention for Mirrors
A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.
A 0.5m diameter ball is at rest on the ground and was placed 2.5m away from a curved mirror that has a radius of curvature of 8m. The ball starts rolling towards the mirror at the speed of 0.8m/s and has a period of 0.5s, until a boy throw the ball straight upward at the speed of 1.75m/s and reached the highest peak at a period of 1.5s.
