1. What is the Frequency Equation?

The frequency equation \( f = \frac{E}{h} \) calculates the frequency of a photon from 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 relationship in quantum mechanics.

3. Importance of Frequency Calculation

Details: Calculating frequency from energy is essential in quantum physics, spectroscopy, and various applications involving electromagnetic radiation and photon energy calculations.

4. Using the Calculator

Tips: Enter energy value in joules. The value must be positive and greater than zero for valid calculation.
