The formula to calculate the energy of a photon (E) from its frequency (v) is:
\[ \text{E} = h \times v \]
Where:
Hz (Hertz) and Joules are units of measurement in physics but they measure different things. Hz is a unit of frequency, measuring the number of cycles per second. On the other hand, Joules is a unit of energy, work, or amount of heat. There isn’t a direct conversion from Hz to Joules because they measure different things.
Let's consider an example:
Using the formula to calculate the energy of the photon:
\[ \text{E} = 6.62607015 \times 10^{-34} \times 5 \times 10^{14} = 3.313035075 \times 10^{-19} \, \text{Joules} \]
This demonstrates that with a frequency of 5 × 1014 Hz, the energy of the photon would be approximately 3.31 × 10-19 Joules.
