Light enters from air into diamond which has refractive index,2.42. The speed of the light in air is 3x108m/s. Calculate speed of light in diamond.?

Question

Answer

Refractive index of Diamond=speed of light/speed of light in diamond
2.42=3 x 10 8/speed of light in diamond
Speed of light in diamond=3x 10 ⁸/2.42
=1.24 x 10 ⁸m/s

Answer

Refractive Index = 2.42
speed of light in air = 3×10 power 8
v =?
n = v1/v2

n=c/v

3×10 power 8/ 2.42 = 1.24 × 10 power 8 m/s

Answer

Speed of 'light' in 'diamond' is

SOLUTION:

The refractive index of an object defines the property the material will show when a light will get refracted from the surface. The exact value in relative to the other refractive index of the other surface is known as absolute refractive index.

Here the value of absolute refractive index is given as:

RI (r) = speed of light in air(c)/speed of light in medium (a)

r= c/a

a = c/r

Absolute refractive index of diamond is 2.4 find the speed of light in diamound if speed of light is 3 * 10 rais to power 8?

Answer

Calculation of Speed of Light in Diamond

Given:
Refractive index of diamond (n) = 2.42
Speed of light in air (c) = 3x108m/s

Formula:
Speed of light in diamond (v) = c/n

Calculation:
Substituting the given values in the formula, we get
v = c/n
v = (3x108m/s) / 2.42
v = 1.24x108m/s

Therefore, the speed of light in diamond is 1.24x108m/s.

Explanation:
- When light enters a medium with a different refractive index, its speed changes.
- The refractive index of a medium is the ratio of the speed of light in vacuum (or air) to the speed of light in that medium.
- In this case, the refractive index of diamond is given as 2.42.
- The speed of light in air is also given as 3x108m/s.
- Using the formula v = c/n, where v is the speed of light in the medium, c is the speed of light in air and n is the refractive index of the medium, we can calculate the speed of light in diamond.
- Substituting the given values in the formula, we get the speed of light in diamond as 1.24x108m/s.
- This means that the speed of light is slower in diamond than in air due to the higher refractive index of diamond.
