Refraction of light causes not only change in velocity of light but also change in wavelength of light but frequency of light remains the same. Explain in details.

Expert Answer:

The frequency cannot change. This is because the fields have to be going up and down 'in step' at the boundary. This is common for all waves that hit the interfaces between two media. The medium only determines the speed of the wave and does not change any portion of the wave. Thus, the refraction of light causes not only change in velocity of light but also change in wavelength of light but frequency of light remains the same.
