"An electromagnetic radiation has a frequency of 5 x 10^14Hz(adsbygoogle = window.adsbygoogle || []).push({});

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?":yuck:

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.
