When a ray of light is refracted by a prism such that the angle of deviation is minimum then A) the angle of emergence is equal to the angle of incidence B) the angle of emergence is greater than the angle of incidence C) the angle of emergence is smaller than the angle of incidence D) the sum of the angle of incidence and the angle of emergence is equal to 90 degrees
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.
When a ray of light is refracted by a prism such that the angle of deviation is minimum then
A) the angle of emergence is equal to the angle of incidence
B) the angle of emergence is greater than the angle of incidence
C) the angle of emergence is smaller than the angle of incidence
D) the sum of the angle of incidence and the angle of emergence is equal to 90 degrees
