Expalin how the frequency remains constant and wavelength changes when light travels from one medium to another by giving suitable examples and photo
Your question is related to Physics, being a physics teacher also I will answer your questios:
When light travels from one medium to another medium of different density the speed(velocity) of the light changes (due to chnage in density) and because of which the pattern of wave propogation also changes i.e. wave length changes. The frequency remains same to keep the equation:- [Velocity=Frequency * Wavelength ] balenced.
