Question

O is a luminescent particle trapped inside a glass block. A student traces the path of rays coming out of it and reflecting over a plane mirror as shown in the diagram below.

Complete the table, using the labels from the figure. The first label is done for you.

a.	An angle of reflection on the mirror	a
b.	A partially reflected ray in the glass slab
c.	A critical angle
d.	A refracted ray
e.	An angle of refraction of the ray R
