What is the speed of light in Lucite What is the speed of li

Solution

According to the given problem,

Speed of light in any material is given by,

V_air/V_material = n_material /n_air

Where n_material for lucite is =1.5 ,n_air =1

V_air value of speed of light in air = 3 *10⁸m/s = c

V_material = V_lucite

V_lucite = c/n_lucite

V_lucite = 3*10⁸/1.5

V_lucite = 2 * 10⁸ m/s
