using conversion factors? PLEASE HELP
wavelength= 6.7 x 10^-5cm
c= 3.00 x 10^10 cm/sec
c/wavelength = frequency, find frequency (hertz)

frequency is cycles per a unit of time. Hertz, the unit for frequency, is cycles in the period of a second. so after you do your c/wavelength, replace (sec) with (hertz)
