Answer:</h3>
3.313 × 10^-34 Joules
<h3>
Explanation:</h3>
The frequency of a photon is 0.5 Hz
Required to find the energy of a photon;
We need to use the formula for energy of a photon;
Energy,E=hf, where h is the plank's constant and f is the frequency of the photon.
Plank's constant, h = 6.626 × 10^-34 J-s
Therefore;
Energy = 6.626 × 10^-34 J-s × 0.5 Hz
= 3.313 × 10^-34 Joules
Thus, the energy of a photon with a frequency of 0.5 is 3.313 × 10^-34 Joules
