A photon goes from vacuum into a medium. This causes its momentum to reduce. Hence by the de Broglie formula, its wavelength should increase.
But, since the refractive index of the medium is greater than 1, and
[tex] n_2/n_1 = \lambda_1 / \lambda_2 [/tex], and hence, its wavelength should decrease.
What am I missing here?
