biggest error in modern physics!! if a ray of light passes from rarer to denser medium, the speed of light decreases, and we know that frequency of light is fixed (coz it stands for the total energy E=hv) since velocity decreases, mass also dec., momentum of photon at the interface decreases!! now using de Broglie wavelenght eqn, lambda increases (lambda = h/p , where p=momentum), that means that means the speed of light increases (= lambda*frequency ), now read the second line again and spot the error!!

now using de Broglie wavelenght eqn, lambda increases (lambda = h/p , where p=momentum),

 that means that means the speed of light increases (= lambda*frequency ),
