An object is placed in front of a concave spherical mirror as shown below. The three rays 1, 2 and 3, leave the top of the object and, after reflection, converge at a point on the top of the image. Ray 1 passes through C, ray 2 passes through F, and ray 3 is parallel to the principal axis. Which ray(s) will reflect back on itself (themselves)? A) both 1 and 2 B) 3 only C) 2 only D) 1 only E) both 1 and 3
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.
