The wavelength of a specific photon in the infrared spectrum is 4 × 10-6 meters. Given that the speed of light is 2.998 × 108 m/s, what would be the frequency of this infrared wave?

Respuesta :

velocity = frequency x wavelength
2.998E8 = f x 4E-6
[tex] \frac{2.998E8}{4E-6} = 7.495E13[/tex] unit of frequency is Hz
7.495E14 
its not 13 i think the person above mistyped and didn't realize it
