Find the velocity of light in diamond. Given the velocity of light in glass is 2 x 10 ms‑1.
Given refractive index of glass with respect to air is 1.5 and that of diamond with respect to air is 2.5.
Answers
n=speed of light in vacuum /speed of light in medium
n=c/v
2.42=3x10^8/speed of light
Speed of light =3x108/2.42
=1.25x108 m/s
Answer:
Explanation:
refractive index of glass with =velocity of light in glass/
respect to air speed of light
1.5 = 2x10^8/speed
speed = 2x10^8/1.5
∴refractive index of diamond with = velocity of light in diamond/
respect to air speed of light
velocity of light in diamond = refractive index x speed
= 2.5 x 2 x 10^8/
1.5
=5x2 x 10^8/
3
=3.33 x 10^8 m/s
