Refraction Of Light Video Lessons

Concept

Problem: Show that when light passes from air to water, its wavelength decreases to 0.750 times its original value.

FREE Expert Solution

The wave speed:

$\overline{){\mathbf{v}}{\mathbf{=}}{\mathbf{f}}{\mathbf{\lambda }}}$

The wavelength of the light changes as the medium changes.

The variation of wavelength with the refractive index is:

$\overline{){\mathbf{\lambda }}{\mathbf{=}}\frac{{\mathbf{\lambda }}_{\mathbf{0}}}{\mathbf{\eta }}}$
