Question 430: Waves Optics

Question

The frequency of a light wave in a material is 2 $$ 	imes $$ 1014 Hz and wavelength is 5000 $$\mathop A\limits^ \circ  $$. The refractive index of material will be

Accepted Answer

By using v = n$$\lambda $$
$$ 	herefore $$ v = 2 $$ 	imes $$ 10
14
$$ 	imes $$ 5000 $$ 	imes $$ 10
-10
= 10
8
m/s
Refractive index of the material,
$$\mu $$ = $${c \over v}$$ = $${{3 	imes {{10}^8}} \over {{{10}^8}}}$$ = 3
