Visiting a jewelry store one evening, you hold a diamond up to the light of a sodium-vapor street lamp. The heated sodium vapor emits yellow light with a frequency of 5.09 x 1014 Hz. Find the wavelength in vacuum and the wave speed and wavelength in diamond, for which K = 5.84 and Km = 1.00 at this frequency. (a) A 90.0 MHz radio wave (in the FM radio band) passes from vacuum into an insulating ferrite (a ferromagnetic material used in computer cables to suppress radio interference). Find the wavelength in vacuum and the wave speed and wavelength in the ferrite, for which K = 10.0 and Km = 1000 at this frequency.
