Question

A light wave moves from a medium where particles of matter are closely packed to a medium made of very little matter. How do you expect the light wave to travel differently?

The light will change wavelength and lose energy.



The wavelength will change along with the frequency.



The wave will move faster, increasing its speed.

Answer 1

The wavelength will chang along with the frequency, I think.  I don't recall why it would lose energy...

Answer 2

"The wave will move faster, increasing its speed" is the way among the following choices given in the question that you can expect the light wave totravel differently. The correct option among all the options that are given in the question is the fourth option or the last option. I hope the answer has come to your help.
