Question

What is the frequency of red light (650 nm) in a vacuum? What is the frequency in medium X, where the
speed of light is only 2.25 x 10^8 m/s? And by how much has the red light's wavelength shifted in medium
X?​

Answer 1

Answer:

1.33

Explanation:

Speed of light in vacuum = 3.0×10 8m/s

Speed of light in water = 2.25×10 8m/s

Refractive index of water = ?

We know that

Refractive index of water = Speed of light in water /Speed of light in vacuumSPJ2

Refractive index of water =

2.25×10 8/3×10 8

=1.33
