Assignment

1. Find the Cauchy’s Constant for a glass prism.
2. Study the variation of refractive index with increasing wavelength.
3. Find the minimum deviation for Red, Yellow, Green, and Blue colours. How does the minimum deviation for different colours change with wavelength?
4. Let the angle of the prism be 50° and the refractive index of the prism be 1.45. Find the angle of minimum deviation.
5. Find the dispersive power of a glass prism using the spectrometer apparatus.
