"An electromagnetic radiation has a frequency of 5 x 10^14Hz
a) (wave in vacuum = 600nm)
b) (wave in water = 440 nm)
c) what is the index of refraction of a medium in which the speed of this radiation is 2.54 x 10^8 m/s?"
so given: c = 2.54 x 10^8 m/s
f = 5 x 10^14Hz
required: ni
im not sure where to start on this one. any help will be appreciated.
