Enter the frequency and Planck’s constant into the calculator to determine the energy of the photon.
Hz To Joules Formula
The following formula is used to calculate the energy of a photon from its frequency.
E = h * v
Variables:
- E is the energy of the photon (Joules)
- h is Planck’s constant (6.62607015 × 10^-34 m^2 kg / s)
- v is the frequency of the photon (Hz)
To calculate the energy of a photon, multiply the frequency of the photon by Planck’s constant. The result will be the energy of the photon in Joules.
What is Hz To Joules?
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. However, in the context of quantum mechanics, the energy of a photon can be calculated from its frequency (in Hz) using the Planck-Einstein relation, E=hv, where E is energy in Joules, h is Planck’s constant, and v is frequency in Hz.
How to Calculate Hz To Joules?
The following steps outline how to calculate the energy of a photon (E) in Joules using the formula E = h * v.
- First, determine the value of Planck’s constant (h). In this case, h = 6.62607015 × 10^-34 m^2 kg / s.
- Next, determine the frequency of the photon (v) in Hz.
- Next, use the formula E = h * v to calculate the energy of the photon (E) in Joules.
- Finally, calculate the energy of the photon (E) using the values of h and v.
- After inserting the values and calculating the result, check your answer with the calculator above.
Example Problem:
