Answer to Question #291874 in Optics for Mark

Question

if the speed of light in air 3 x 10 ⁸ m/s find the speed of light in diamond of refraction index 2.419

Answer 1

Answer

speed of light in air c=3 x 10 ⁸ m/s

refraction index n=2.419

Speed of light in diamond

$v=\frac{c}{n}\\=\frac{3 *10 ⁸}{2.419}\\=1.24*10 ⁸m/s$
