Question

why frequency changed but wavlenght same when light passes through medium​

Answer 1

Answer:

hey mate......

here is your answer....

as a wave travels into a denser medium, such as water, it slows down and the wavelength decreases. Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes.
