1. What is the Frequency Equation?

The frequency equation \( f = \frac{E}{h} \) calculates the frequency of a photon based on its energy, where E is the energy in joules and h is Planck's constant (6.626×10⁻³⁴ J·s).

2. How Does the Calculator Work?

The calculator uses the frequency equation:

Where:

• \( f \) — Frequency (Hz)
• \( E \) — Energy (J)
• \( h \) — Planck's constant (6.626×10⁻³⁴ J·s)

Explanation: This equation relates the energy of a photon to its frequency through Planck's constant, a fundamental constant in quantum mechanics.

3. Importance of Frequency Calculation

Details: Calculating frequency from energy is essential in quantum physics, spectroscopy, and understanding the behavior of electromagnetic radiation and particles at the quantum level.

4. Using the Calculator

Tips: Enter energy in joules. The value must be valid (energy > 0).

5. Frequently Asked Questions (FAQ)
