A light wave travels from air into a medium of refractive index is 1.54,if the wave lenght of the light in air is 5.49×10^-7. Calculate its wave lenght in the medium
The formula to calculate the wavelength of light in a medium is given by:
λ_medium = λ_air / n
where:
λ_medium = wavelength of light in the medium
λ_air = wavelength of light in air
n = refractive index
Given:
λ_air = 5.49×10^-7
n = 1.54
Plugging these values into the formula:
λ_medium = 5.49×10^-7 / 1.54
λ_medium = 3.56×10^-7
Therefore, the wavelength of the light in the medium is 3.56×10^-7.
