I've seen a mathematical example where a wave was made from same source in water and air. but in both medium frequency was same but wavelengths were different in each medium. we know that velocity of a wave = frequency * wavelength. if the velocity of a wave changes from medium to medium(wave;in two different medium but made from same source) why doesn't the frequency change (in case of a wave which is made from same source)?

- What determines color -- wavelength or frequency?
- Why doesn't the frequency of light change during refraction?
