so you're saying the answer is wrong because blue and red are not deflected the same amount?
also, how do i find the speed of the electromagnetic waves through another media if i don't know it's n? or how can i use frequency of that wave to find the speed as it travels through another medium?
so is there a similarity between dispersion and refraction, because refraction deals with snells law?
there was a question on a practice test i took with the question:
if two monochromatic beans of red and violet light are shone upon a thin film (n = 1.3), which color of light is deflected...
i'm getting confused. so when white light diffracts, red light will bend the most and blue light will bend the least. but when white light disperses, blue light will bend the most, but white light will bend the least? I'm not understanding why.
and also i read somewhere that the angle of...
