Had an exam question today where a beam of light travels through air then water - refracting.
It said - 'what happens to the wavelength of the light when it enters the water?' for 1 mark. I put that it stays the same.
Any ideas on if it was right? Thanks!

Does the wavelength of light change when it refracts? watch

Refraction is the change of speed when a wave goes from one medium to another.
As frequency remains constant wavelength does change.
