O a. the period is directly proportional to the wavelength of an EM wave
O b. the period is the same for every ray within the EM spectrum
O c. the period is inversely proportional to the wavelength of an EM wave
O d. wavelength and frequency are equal.
O e. the period is the square of the wavelength of an EM wave
