Question

Calculate the ratio of the energy of the photon $A$ to the energy of the photon $B$ if frequency of the photon $A$ is twice the frequency of the photon $B$.

• A. 4
• B. 2
• C. 1
• D. $\frac{1}{2}$
• E. $\frac{1}{4}$

Answer 1

The correct option is B 2

Since the energy of a photon is proportional to its frequency, twice the frequency will give twice the energy.
