Okay, I just need to grasp what the equation C = Vλ means(adsbygoogle = window.adsbygoogle || []).push({});

.

Correct me if I am wrong.

c = speed of light

v = speed of frequency

λ = wavelength

So if I wanted to find the speed of the frequency of a photon with a wavelength of 450nm

So I would use

v = c/λ

v = 299,792,458/4.5 * 10^(-11)

= 6.662054622 * 10^18

Then, if I wanted to find the energy of the photon, I would just multiply that number by planks constant (6.26 * 10^-34) and I get the energy of a quantum leap from an atom and the photon's energy itself, right?
