Question

State two precautions taken in the experiment of glass prism​

Answer 1

Here are two precautions that are taken in the experiment of a glass prism:

1. Cleaning the prism: Before conducting the experiment, it is important to ensure that the prism is clean and free of any dirt or dust particles. Any impurities on the surface of the prism can affect the way the light passes through it and can lead to inaccurate results. Therefore, the prism should be cleaned using a soft cloth or tissue paper to avoid any scratches on the surface.

2. Placing the prism correctly: To obtain accurate results in the experiment, the prism should be placed correctly in the path of the light beam. The angle of incidence and angle of deviation should be measured carefully, and the prism should be adjusted accordingly to ensure that the light passes through it at the correct angle. A small deviation in the placement of the prism can lead to significant differences in the results obtained, so it is important to be precise in the placement of the prism.

Answer 2

"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
