This photon energy calculator will help you determine a photon’s energy based on its wavelength.

**Explanation:**

This photon energy calculator allows you to compute the energy of a photon based on its wavelength or frequency. The calculations are based on the following fundamental physics equations:

- The speed of light, (c = 3 times 10^8) meters per second
- Planck’s constant, (h = 6.626 times 10^{-34}) Joule seconds
- The relationship between wavelength and frequency: ( c = lambda nu )
- The energy of a photon: ( E = h nu )

You can enter either the wavelength or the frequency, and the calculator will compute the corresponding photon energy and display the result.

**How to Use:**

To use the calculator, follow these steps:

- Enter the wavelength in meters in the “Wavelength” field.
- Or, enter the frequency in Hz in the “Frequency” field.
- Click the “Calculate” button.
- The photon energy will be displayed in the “Photon Energy” field.
- The result will be displayed in the “Result” field.

**How It Calculates the Results:**

With the given wavelength ((lambda)):

- The frequency ((nu)) is calculated using the formula ( nu = frac{c}{lambda} ).
- The photon energy ((E)) is then calculated using the formula ( E = h nu ).

Likewise, if the frequency ((nu)) is provided directly:

- The photon energy ((E)) is calculated using the same formula ( E = h nu ).

**Limitations:**

This calculator assumes a vacuum for the speed of light. In different mediums, the speed of light may vary, which is not accounted for in this calculation. The result is based on fundamental physical constants and may have limitations in extreme conditions or for highly accurate precision requirements.
