Assignment:

1. Find the Cauchy's Constant for glass prism.

2. Study the variation of refractice index with increasing wave length.

3. Find the minimum deviation for Red, Yellow, Green and Blue colour. How minimum deviation of different colour changes with wave length?

4. Let the angle of the prism is 50 degree and refractive index of the prism is 1.45. Find the angle of minimum deviation.

5. Find the dispersive power of a glass prism using spectrometer apparatus.
