1. What is the Photon Frequency Equation?

The photon frequency equation relates the energy of a photon to its frequency using Planck's constant. This fundamental relationship in quantum mechanics is described by the equation f = E/h.

2. How Does the Calculator Work?

The calculator uses the photon frequency equation:

Where:

• \( f \) — Frequency (Hz)
• \( E \) — Energy of the photon (J)
• \( h \) — Planck's constant (6.62607015 × 10⁻³⁴ J·s)

Explanation: The equation shows that the frequency of a photon is directly proportional to its energy and inversely proportional to Planck's constant.

3. Importance of Frequency Calculation

Details: Calculating photon frequency is essential in quantum mechanics, spectroscopy, and understanding electromagnetic radiation. It helps determine the color of light, energy transitions 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 Planck's constant?
A: Planck's constant (h) is a fundamental physical constant that relates the energy of a photon to its frequency. Its value is approximately 6.626 × 10⁻³⁴ J·s.

Q2: How is frequency related to wavelength?
A: Frequency and wavelength are related by the speed of light: c = λf, where c is speed of light, λ is wavelength, and f is frequency.

Q3: What are typical photon energies?
A: Visible light photons have energies around 10⁻¹⁹ J, while X-ray photons have energies around 10⁻¹⁵ J.

Q4: Can this equation be used for all particles?
A: This specific form applies to photons. For matter particles, the de Broglie wavelength equation is used.

Q5: Why is the frequency important?
A: Frequency determines the photon's position in the electromagnetic spectrum and its interaction with matter.
