Question

in a dense medium the speed of light is less because there is more consumption of energy, so when a ray enters from a denser medium to rarer medium, then it should have lost enough energy to gain the speed in that particular medium, so how can we say that the speed of light is higher in rarer mediums?

Answer 1

Answer:

According to Snell's Law: sin isin r = n2n1 = v1v2 Rarer medium will have refractive index n2 less than refractive index n1 of denser medium. Thus, according.

Answer 2

Answer:

know it does not because it emerges out of denser medium at 300,000 KM per second, but according to E=mc2 and given that speed of light decreases inside denser medium with refractive index greater than 1, does not it suggest that energy of light inside denser medium is less?
