Looking at the electromagnetic spectrum, the product of wavelenght and frequency of a wave is constant. For example, Gamma Rays; wavelenght 3e-14 m x frequency 10^22 Hz = 300 000 000. The same number is given for the product of all waves on the spectrum. My question is: If: [tex]c=\lambda\nu[/tex] and [tex]\lambda\nu=3 e8[/tex] How does 300 000 000 come out to 299792 km/s???
