white light passes through prism . compared with blue light, the red light is ,
a) slowed down less and refracted less
b) slowed down less and refracted more
c) slowed down more and refracted less
d)slowed down more and refracted more
ans with explaination, arigato xD

Hi Yihao,
Red light is slowed down less and refracted less.
It is faster than blue light as it has a lower frequency, and it is refracted less as it has a longer wavelength.
Cheers.

Hi Yihao,
Do have a look at Page 4 of this article:
