# Problem: Part AWhat is the speed of light in ethyl alcohol (n = 1.36)?Part BWhat is the speed of light in lucite (n = 1.50)?Part CWhat is the speed of light in crown glass (n = 1.52)?

###### FREE Expert Solution

Speed of light is given by:

$\overline{){\mathbf{v}}{\mathbf{=}}\frac{\mathbf{c}}{\mathbf{\eta }}}$

Where c is the speed of light in a vacuum, c = 3.0 × 108 m/s
