In order to calculate the refractive index of a certain glass a young engineering student decided to build an apparatus, as shown in the picture below. Basically he took two mirrors of equal thickness t and focused a beam as indicated. After passing through a lens, a pattern is formed on a bulkhead ahead. How was the student able to estimate the index of refraction? A) by changing the distance between the mirrors we change the pattern into light and dark bands B) by using the apparatus described there is no way to determine the refractive index of glass C) by changing the distance between the mirrors and the screen (or laser) the pattern changes into light and dark bands D) in the screen we will have an interference pattern s
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.

C) by changing the distance between the mirrors and the screen (or laser) the pattern changes into light and dark bands
D) in the screen we will have an interference pattern similar to a double slit where we have a central maximum and other maximums relating to different reflections of the mirror
