    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!

    Refraction is the change of speed when a wave goes from one medium to another.

    As frequency remains constant wavelength does change.

    v=f*lamda
