Backend Formula for the Photon Energy Calculator
The Photon Energy Calculator relies on the fundamental formula E = hν, where E is the energy of the photon, h is Planck’s constant (6.626 × 10-34 J·s), and ν is the frequency. Alternatively, energy can be calculated using E = hc/λ, with c representing the speed of light and λ the wavelength.
For example, if a photon has a frequency of 5 × 1014 Hz, its energy is calculated as follows:
- Step-by-step Calculation: E = 6.626 × 10-34 J·s × 5 × 1014 Hz = 3.313 × 10-19 J
These formulas allow for different approaches depending on available data, providing flexibility and precision.
Step-by-Step Calculation Guide for the Photon Energy Calculator
To manually calculate photon energy, consider these steps:
- Determine the frequency from the wavelength, if needed, using ν = c/λ.
- Apply the formula E = hν or E = hc/λ.
- Ensure all units are consistent to avoid errors.
Consider an example where the wavelength is 600 nm:
- Convert wavelength to meters: 600 nm = 600 × 10-9 m.
- Calculate frequency: ν = 3 × 108 m/s ÷ 600 × 10-9 m = 5 × 1014 Hz.
- Determine energy: E = 6.626 × 10-34 J·s × 5 × 1014 Hz = 3.313 × 10-19 J.
These examples illustrate how variations in input significantly affect outcomes.
