A light beam propagates two times slower when it passes from medium-1 to medium-2. If the wavelength in medium-1 is 1 = 750 nm, and the index of refraction in medium-2 is n2 = 2.8, then the frequency of light is: (Take speed of light in vacuum c = 3 x 10^8 m/s) f= 4.28 x 10*14 Hz f= 0.47 x 10*14 Hz O f= 1.43 x 10^14 Hz O f = 0.71 x 10^14 Hz f = 2.86 x 10^14 Hz
