## what is atmospheric refraction? how we can say that a chick manage to awake early in the morning?

## A ray of light is refracted through a 60 degree prism of ordinary glass making an incident of 35 degree with the normal i.e incident ray =35°.What will the angle of emergent ray and the angle of deviation measure?

## I just get to know that when light passes through optical centre then it shows very very slight deviation which we neglect but when light passes through optical centre then actually light is falling along normal(normal incidence) , in that case angle of incidence is 0 and thus angle of refraction is also 0 (by snell's law) so even that slight deviation should'nt be there( i know it is very very slight deviation, but afterall it is a deviation)
