Question

can a glass slab bend different coloured lights by different amount

Answer 1

Refraction

Explanation:

• Refraction is the phenomenon of deflection of light when it passes through two mediums of varying density.

• The index of refraction of different material is dependent on the wavelength of the light, hence lights of different wavelength are bent differently  due to refraction.

• When light travelling through the air enters the glass slab, it gets refracted and tilts toward the normal. The direction of the refracted ray changes again when it comes out of the glass slab, while coming out from the slab it bends away from the normal.

Answer 2

Answer:

Yes, a glass slab bends different colored lights in different amounts. Light of different wavelengths are bent differently due to refraction. But after emerging from other parallel side, these colored lights converge and no colorful effect is observed.
