Answer 1

"The two precautions that must be taken while preforming the experiment of tracing the path of rays of light through a glass prism are

1. Make sure Glass of slab is clean and it must be free from air bubbles.

2. Also, the Angle of incidence should be lies between 30 degree and 60 degree

"

Answer 2
