TBR Physics Book II page 283 #30
“When white light passes from air to a prism, what is true?”
Answer: Light with the highest frequency is refracted by the greatest amount [I agree]
Incorrect Answer: Light with the greatest speed is refracted by the greatest amount
TBR says that “light traveling through a medium will exhibit the same wave speed regardless of frequency”
I’m pretty sure that TPR says that when light passes through a material medium, waves of different frequencies have different speeds (TPR says this is the one exception to the general idea that frequency is independent of speed).
More specifically, TPR says that higher frequency waves (violet) would be slower. This wouldn’t change the answer to the TBR question at hand but it does go against the logic in the answer explanation.
