They are asking the find the deviation d?
I know by snell's law n = sin i/sin r
where n is refractive index, i is angle of incidence and r angle of refraction.
so sin r = sin i/1.5 which gives 15 minutes(roughly) as the angle of refraction. but i dont know how to calculate d in cms. Please help, revered members
