Which of the following choices give a correct relationship between the frequency and the wavelength of electromagnetic radiation?
Since more than one choice is correct, points will be deducted for incorrect choices.
Select one or more:
a. frequency times the speed of light equals the wavelength
b. frequency is equal to the speed of light divided by the wavelength
c. the wavelength equals frequency divided by the speed of light
d. the wavelength is inversely proportional to the frequency
e. frequency times wavelength is equal to the speed of light
f. the wavelength is proportional to the frequency
