Sagot :

Given that the light passes from air to glass, that means it enters to denser medium from rarer medium.

Here, air is the rarer medium and glass is the denser medium.

Speed decreases when light enters from rarer to densr medium , while the frequency remains the same and its wavelength becomes shorter.

Thus, option C is correct.
