Q2 of 123 Page 410

Can you ever have a situation in which a light ray goes un-deviated through a prism?

Yes, definitely, when the incidence angle of light rays over one surface of prism perpendicularly, that is incidence angle is 0, . Here i, A, and e becomes 0. Hence deviation is also 0. Also we can find such cases of ‘dispersion without deviation’
