An electromagnetic wave of frequency 5.0 x 1014Hz, is incident on the surface of water of refractive index \(\frac{4}{3}\). Taking the speed of the wave in air as 3.0 x 108ms-1, calculate the wavelength of the wave in water.
A. 2.2 x 10-6m B. 1.7 x 10-7m C. 8.0 x 10-7m D. 6.0 x 10-7m E. 4.5 x 10-7m
