1. What is the Frequency Equation?

The frequency equation calculates the frequency of a photon from its energy using Planck's constant. It's derived from the fundamental relationship between energy and frequency in quantum mechanics.

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 represents the fundamental quantum mechanical relationship where the energy of a photon is directly proportional to its frequency.

3. Importance of Frequency Calculation

Details: Calculating frequency from energy is essential in quantum mechanics, spectroscopy, photonics, and various fields of physics and chemistry where the energy-frequency relationship is fundamental.

4. Using the Calculator

Tips: Enter energy in joules (J). The value must be positive and greater than zero. Planck's constant is fixed at 6.626 × 10⁻³⁴ J·s.
