The wavelength of a specific photon in the infrared spectrum is
4 × 10^-6 meters. Given that the speed of light is 2.998 × 10^8 m/s, what would be the frequency of this infrared wave?
11.992*10^2 Hz
0.7495*10^-14 Hz
11.992 * 10^-2 Hz
0.7495 * 10^14 Hz

speed of light = wavelength x frequency
frequency = speed of light/ wavelength
do the math!!

@Cuanchi if I knew how to do the math I wouldn't be on here

@whateven we need to understand the units first, I agree with what @Cuanchi said
