Question

the speed of light in diamond is 125000km per second . what is its refractive index?​

Answer 1

Answer:

2.4

Explanation:

According to the given question,

v = speed of light in medium = 125000 km/s

(Here medium is diamond)

c = speed of light in vacuum = 300000 km/s

n = refractive index of the material.

(Here material is diamond)

We know,

• n = c/v

Putting the values we get,

• n = 300000/125000

• n = 300/125

• n = 2.4

Thus refractive index of the diamond is 2.4 (approx).
