When an electromagneticwave travels from a medium to the other,its wavelength changes but its frequency remains constant. So the energy also changes.If we consider a particular photon,its frequency does not change so its energy should not change as energy = h.Also the wavelength of the photons change in the above conditions,so its energy should change as Energy = hc/.So what is the reason of this contradiction and what actualy happens?
