Hi, I was doing this FL through BR, and I am a bit confused as to why the answer, I always thought that faster speeds of light have shorter wavelengths and higher frequencies, somewhere from my Physics class! If anyone can help clarify this for me, I would really appreciate it!
Here is the passage.
"If light passes from Medium A with an angle of incidence of 40° to the normal into Medium B with a refracted angle of 30° to the normal, what changes are observed in the speed and wavelength of the light in the two mediums?
answer:
It is faster and has a longer wavelength in Medium A than in Medium B.
C is the best answer. Because the angle of refraction is smaller than the angle of incidence, we know that the light ray is bent toward the normal as it passes from Medium A into Medium B. That means Medium B must be denser than Medium A, so the speed (v) of the light ray slows down slightly, although its frequency (f) remains constant. "
