The wavelength of red light in a vacuum is 720 nm. determine the wavelength of red light in an environment in which the speed of light is 200,000 km / s.
Wave refractive index:
n = c / v
n = (3 * 10 ^ 8) / 2 * 10 ^ 8
The length of red in a transparent medium will be:
λ = λ0 / n = 720 / 1.5 = 480 (nm)
Answer: λ = 480 (nm)
