The energy of a photon with frequency $\nu$ is given by which of the following expressions?
- A.$E = h / \nu$
- B.$E = h \nu$
- C.$E = \nu / h$
- D.$E = h \nu^2$
Show correct answer & step-by-step solution
Correct answer: B — $E = h \nu$
Solution
According to Planck's quantum theory, the energy of a photon is directly proportional to its frequency, expressed as , where is Planck's constant.
