Answer 1

The index of refraction of diamond is 2.0, velocity of light in diamond in cm/second is approximately

mark as brillienst answer

Answer 2

Answer: 1.5 x 10^10 cm/s

Step-by-step explanation:

using formula  u=c/v

given: u=2.0(refractive index of diamond)

c=3 x 10^8 (speed of light in air or vacuum)

Therefore  2.0 =3 x10 ^8 / v

v=3 x 10^8 / 2.0 = 1.5 x 10^8 m/sec

velocity of light in cm/sec----

1.5 x 10^8 x 10^2= 1.5 x 10^10
