Minimum Deviation — Prelims Questions

A ray of light passes through an equilateral glass prism such that the angle of incidence is equal to the angle of emergence. If the angle of emergence is $45^circ$, what is the angle of minimum deviation for the prism?

A prism has a refractive index of $sqrt{2}$ and a prism angle of $60^circ$. What is the angle of minimum deviation for this prism?

Which of the following statements is TRUE regarding the condition of minimum deviation for a prism?

For a thin prism of angle $A$, the angle of minimum deviation $D_m$ is given by $(n-1)A$. This approximation is valid when:

A ray of light is incident on one face of a prism at an angle of $60^circ$. The angle of the prism is $60^circ$. The ray suffers minimum deviation. The angle of deviation is $30^circ$. What is the angle of refraction inside the prism at the first surface?

When white light passes through a prism, which color deviates the most at minimum deviation?
