A light ray comes directly at a surface and makes a right angle with the surface

Question

A light ray comes directly at a surface and makes a right angle with the surface. What is the angle of incidence?

What are the units for the slope of your graphs?

What is the approximate value of the slope of your curves?

When you change from blue to red light, how does the slope of your curve change?

The angles of incidence and reflection are measured with respect to the normal (line perpendicular to the mirror surface). If you measured these angles with respect to the mirror surface, how would the slopes on your graphs change?

What is the dependent variable for the graphs in this lab?

The rear surface mirror reflects light at a different angle than the front surface mirror.

In this lab you have seen light of many different colors reflected by a front surface mirror. What would you expect to happen if the red light used on the front surface mirror was reflected using a rear surface mirror?

A light ray comes directly at a surface and makes a right angle with the surface. What is the angle of incidence?

Explanation / Answer

1. Option A

The angle between incident ray and normal to surface is called angle of incidence.

Here incident ray is normal to surface so angle of incidence is 0°
