In vacuum, an electromagnetic wave has speed c = 2.9979 × 108 m/s and frequency f = 6.0 × 1014 Hertz. It enters a material whose index of refraction is n = 1.40.
(a) Obtain the speed of the wave in the material.
(b) Obtain the frequency of the wave in the material.
(c) Obtain the wavelength of the wave in the material.
