1. What is the Frequency of a Photon Equation?

The frequency of a photon equation relates the frequency of electromagnetic radiation to its wavelength through the speed of light. This fundamental relationship is crucial in quantum mechanics and electromagnetic theory.

2. How Does the Calculator Work?

The calculator uses the photon frequency equation:

Where:

• \( f \) — Frequency in Hertz (Hz)
• \( c \) — Speed of light in vacuum (299,792,458 m/s)
• \( \lambda \) — Wavelength in meters (m)

Explanation: The equation shows that frequency is inversely proportional to wavelength - as wavelength increases, frequency decreases, and vice versa.

3. Importance of Frequency Calculation

Details: Calculating photon frequency is essential for understanding electromagnetic wave properties, quantum energy levels, and applications in spectroscopy, telecommunications, and photonics.

4. Using the Calculator

Tips: Enter wavelength in meters and speed of light in m/s (default is vacuum speed). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why doesn't distance affect frequency?
A: Frequency is an intrinsic property of the photon determined at emission. While distance affects intensity, the frequency remains constant.

Q2: What are typical frequency ranges?
A: Radio waves: 3kHz-300GHz, Visible light: 400-790THz, X-rays: 30PHz-30EHz.

Q3: How does this relate to photon energy?
A: Energy is calculated by \( E = hf \), where h is Planck's constant (6.626×10⁻³⁴ J·s).

Q4: Does medium affect the calculation?
A: In different media, the speed of light changes, so use the appropriate speed for that medium.

Q5: Can this calculate wavelength from frequency?
A: Yes, by rearranging the equation: \( \lambda = c/f \).
