Hi I was told by physics lecturer that both the wave speed and wave length of light changes when it enters a medium, however I questioned this stating that if both wave speed and wave length changed then frequency must also according to the formula c = fλ. He stated that "frequency is energy and energy is conserved"
I was wondering if I would be able to get a more in depth answer from someone here and correct my lecturers statement.
