Question

Spectral line with frequency of 3.5 times 10^12 hertz. Whats the energy of a photon of this frequency?

Answer 1

The Plank relation for the energy \(E\) in \([\text J]\),

of a photon with frequency \(f\) in \([\text{Hz}]\)

is \[E=hf\]_______

Where \(h\) is planks constant \(6.63\times10^{-34}[\text J\cdot\text s]\)
