this is my first post in this forum.
i have a question :
i have read that when light refracts into other medium its frequency remains unchanged but velocity and wavelength changes.
there is a formula to it : v=n*lamda (v=velocity,n=freq,lambda=wavelength)
Q1: why the freq remains unchanged ?
Q2: is it true for all waves (like sound, etc ) ?
thank you
