Question

anonymous · Answer

The refractive index of a material depends on wavelength. This phenomenon is called dispersion.

@Calculator  according to me the answer is NO,,,,,when the light(red+blue) enters the glass slab,,,,as Gyanu said,,, dispersion takes place and the colours get separated,,,,,but when they come out of the glassslab ,they recombine to give u the original light(red+blue)

anonymous · Answer

it will propagate in the same direction ,,but it gets shifted
