An engineer has built a device with two plane mirrors at right angles to one another. He directs a light ray toward Mirror 1, at an incidence angle of ?1 = 35.6°. The light ray travels within a plane that is perpendicular to both mirrors. The ray strikes Mirror 1, as shown below, and is reflected toward Mirror 2, where it undergoes a second reflection before leaving the device. A)How far (in m) does the light ray travel between the two mirrors? B)With what angle of reflection, ?2, measured from Mirror 2's normal line, does the ray depart Mirror 2 after the second reflection in 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.
