Question

Binding of light occurs in a glass slab also, but net deviation is Zero. Why is it so in the case of
prism?

Answer 1

Answer:

In glass slab two refracting surfaces are parallel to each other they just displace the light ray they don't deviate the rays. In prism two refracting surfaces are inclined to each other the deviate the light rays. According_to colour and wavelength of light violate light deviate more and red deviate least.
