Refraction of Light Watch
I got the following question wrong:
"A ray of blue light is incident on the liquid surface at the same angle as the ray of red light.
The refractive index of the liquid for blue light is greater than that for red light. Is the angle of refraction greater than, equal to or less than 82 degrees for the blue light?
You must explain your answer"
And my answer was:
"The greater the refractive index of a material, the higher the frequency and the slower that light travels in that material, therefore the light will refract more and the angle of refraction for blue light will be smaller than 82 degrees."
I just can't see where I've went wrong, and it would be massively appreciated if someone could tell me what I have done incorrectly.
I'm not sure where the 82 degrees comes from, but because the blue light refracts more than the red light, its angle of refraction would be greater than the angle of refraction of the red light, not smaller.
FYI: 82 degrees was an angle given in the question previous.
