The answer given by Claude Bile seems more reasonable to me, thank you all.

Well and good bp_psy, but i want to know why we always say that wavelength changes and frequancy remains the same as the speed of the wave (it will be better consider light waves) took a different value upon refraction.

When light or any other electromagnetic wave enters from one medium to another, there is a change in its speed. Speed of a wave is given as v = frequency x wavelength. My question is, what does change, frequency, wavelength or both? If you say... this change in speed is generally attributed...
