Refraction Of Light Video Lessons

Concept

# Problem: When light wave travels from air into glass itsa) speed remains the same, b) speed increases, c) wavelengths increases, d) wavelength remain the same, e) frequency remains the same

###### FREE Expert Solution

In this question, we are required to determine the effect of change of medium on the frequency, wavelength and velocity of waves.

Refractive index:

$\overline{){\mathbf{\eta }}{\mathbf{=}}\frac{\mathbf{c}}{\mathbf{v}}{\mathbf{=}}\frac{{\mathbf{\lambda }}_{\mathbf{0}}}{\mathbf{\lambda }}}$ λ0 is the wavelength in vacuum.
