The variation of refractive index of a crown glass thin prism with wavelength of the incident light is shown. Which of the following graphs is the correct one, if is the angle of minimum deviation?
Options:
Answer:
A
Solution:
When angle of prism is small, then angle of deviation is given by So, if wavelength of incident light is increased, decreases and hence decreases.
