We know that,
Wavelength of light in a material:
λ= λ0/n
where, λ=wavelength of material, λ0=wavelength of light in vacuum,
n=index of refraction of material.
So, 650x10-9m/1.47=442.177nm.
Wavelength of light in a material:
λ= λ0/n
where, λ=wavelength of material, λ0=wavelength of light in vacuum,
n=index of refraction of material.
So, 650x10-9m/1.47=442.177nm.

Calculation of wavelength in liquid
Given:
Wavelength of light in vacuum (λ0) = 650 nm
Index of refraction of liquid (n) = 1.47
To find:
Wavelength of light in the liquid (λ)
Solution:
The relationship between the wavelength of light in vacuum and the wavelength of light in a medium is given by:
n = λ0/λ
where n is the refractive index of the medium.
Rearranging the above equation, we get:
λ = λ0/n
Substituting the given values, we get:
λ = 650 nm / 1.47
λ = 442 nm
Therefore, the wavelength of the light in the liquid is 442 nm. Hence, option (B) is the correct answer.
