A monochromatic light wave travels from Medium 1 (air, refractive index n=1.0n = 1.0n=1.0) into Medium 2 (glass, refractive index n=1.5n = 1.5n=1.5) as shown below.
The wavelength of the light in Medium 1 is 600 nm600\text{ nm}600 nm, and the speed of light in Medium 1 is 3.0 × 108 m s-1.
What are the frequency f2 f_2\,f2 and the wavelength λ2 \lambda_2\,λ2 of the light inside Medium 2?
