1. What is Photon Frequency?

Photon frequency (f) is the number of wave cycles that pass a given point per unit of time, measured in Hertz (Hz). It's directly related to the energy of the photon through Planck's equation.

2. How Does the Calculator Work?

The calculator uses the photon frequency equation:

Where:

• \( f \) — Frequency (Hz)
• \( E \) — Photon energy (Joules)
• \( h \) — Planck's constant (6.62607015 × 10⁻³⁴ J·s)

Explanation: The equation shows the direct proportionality between a photon's energy and its frequency.

3. Importance of Photon Frequency Calculation

Details: Calculating photon frequency is essential in quantum mechanics, spectroscopy, and understanding electromagnetic radiation properties. It helps determine the color of light, energy levels in atoms, and more.

4. Using the Calculator

Tips: Enter photon energy in Joules and Planck's constant in J·s (default value is provided). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range of photon frequencies?
A: Photon frequencies range from radio waves (few Hz) to gamma rays (10²⁰ Hz and above).

Q2: How is frequency related to wavelength?
A: Frequency and wavelength are inversely related through the speed of light: \( c = \lambda \times f \).

Q3: Why is Planck's constant important?
A: Planck's constant relates the energy of a photon to its frequency, fundamental to quantum mechanics.

Q4: Can this calculator be used for all electromagnetic radiation?
A: Yes, the equation applies to all photons across the electromagnetic spectrum.

Q5: What if I know the frequency and want to find energy?
A: Simply rearrange the equation: \( E = h \times f \).
