प्रश्न
Light of wavelength 5000 Å propagating in air gets partly reflected from the surface of water. How will the wavelengths and frequencies of the reflected and refracted light be affected?

उत्तर
The frequency and wavelength of reflected wave will not change.
The refracted wave will have same frequency.
The velocity of light in water is given by
v=λf
where
v = Velocity of light
f = Frequency of light
λ = Wavelength of light
If velocity will decrease, wavelength (λ) will also decrease.
