refraction varies with wavelength

Controls

A prism bends violet light more than red because the refractive index depends on wavelength — splitting white light into a rainbow, exactly as Newton showed.

Snell's law of refraction

n_{1} sin θ_{1} = n_{2} sin θ_{2} : 1.00 sin 3 5^{\circ} = 1.55 sin θ_{2} \Rightarrow θ_{2} = 21. 7^{\circ}

Reading this result: At 1× dispersion and a 35° exit angle, each wavelength refracts by a slightly different amount, splitting white light into an ordered ROYGBIV band.
