The wavelength of the radio wave in water is 222nm
The relationship between the refractive index wavelengths in a vacuum and in water is given by:
n = λ1/λ2
So,
let λ1 be the wavelength of light in a vacuum
λ2 be the wavelength of light in water.
nwater = 1.33
Plugging in values, we have
n = λ1/λ2
1.33 =295 m /λ2
λ2 = 295 m/1.33
= 221.80nm
≈222nm
Therefore the wavelength of radio wave in water is 222mn.
