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.
| S. No. | Description | Label |
|---|---|---|
| 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 |
