Do we essentially measure its wavelength and calculate the frequency?
I thought we figured out frequencies by refracting the light into its many frequencies - (ie, like we see when looking at a Doppler shift). But, refraction formulas are based on VELOCITY, not wavelength and light travels at a constant speed.
So, given a hypothetical situation of slowing down light (possible through denser mediums), would the colours refract at the same angles - since the wavelengths are the same, or would they refract differently since the speeds are different (assuming you manage to keep the transition from one medium to another the exact same ratio)
Thanks!
