Question

A light wave of frequency 5 \(\times\) 10\(^{14}\)Hz moves through water which has a refractive index of \(\frac{4}{3}\). Calculate the wavelength in water if the velocity of light in air is 3 \(\times\) 10\(^8\) m/s.

Options

A) 4.5 \(\times\) 10\(^{-7}\)m

B) 6.0 \(\times\) 10\(^{-7}\)m

C) 1.7 \(\times\) 10\(^6\)m

D) 2.2 \(\times\) 10\(^6\)m
