The index of refraction of the medium where the speed of light is 1.24× 10⁸m/s, is 2.42.
To find the answer, we need to know about the relation between the refractive index and velocity of light.
<h3>What's the the expression of refractive index of a medium in term of velocity of light?</h3>
- Refractive index of any medium (n)= C/V
- C= speed of light in vaccum which is 3×10⁸ m/s , V = velocity of light in the medium
<h3>What's the refractive index of a medium in which speed of light is 1.24 x 10⁸ m/s?</h3>
Refractive index of the medium =
3×10⁸/1.24 x 10⁸
= 2.42
Thus, we can conclude that the refractive index of the medium is 2.42.

Answer:
Explanation:
The energy of a photon is given by:
(1)
Where:
is the Planck constant
is the frequency light
On the other hand, there is an inverse relationship between and the wavelength :
(2)
Where:
is the speed of light
is the wavelength
Substituting (2) in (1):
(3)
Finally:
This is the energy of a photon of blue light, in Joules.
D) gas to a solid because the particles are slowing down and there not colliding with each other
