1. What is Frequency of Light?

Frequency of light refers to the number of wave cycles that pass a given point per second. It is inversely proportional to wavelength and is a fundamental property of electromagnetic radiation, including visible light.

2. How Does the Calculator Work?

The calculator uses the frequency formula:

Where:

• \( f \) — Frequency (Hz)
• \( c \) — Speed of light = 3×10⁸ m/s
• \( \lambda \) — Wavelength (m)

Explanation: The formula shows that frequency and wavelength are inversely related - as wavelength increases, frequency decreases, and vice versa.

3. Importance of Frequency Calculation

Details: Calculating light frequency is essential in various fields including optics, telecommunications, spectroscopy, and quantum mechanics. It helps determine the energy of photons and classify electromagnetic radiation.

4. Using the Calculator

Tips: Enter wavelength in meters. The value must be positive and greater than zero. The calculator will compute the corresponding frequency in hertz (Hz).

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between frequency and wavelength?
A: Frequency and wavelength are inversely proportional. As frequency increases, wavelength decreases, and vice versa.

Q2: What is the speed of light value used in calculations?
A: The calculator uses c = 3×10⁸ m/s, which is the speed of light in vacuum.

Q3: Can I use different units for wavelength?
A: The calculator requires meters. Convert other units (nm, μm, etc.) to meters before calculation.

Q4: What is the typical frequency range of visible light?
A: Visible light frequencies range from approximately 4.3×10¹⁴ Hz (red) to 7.5×10¹⁴ Hz (violet).

Q5: How does frequency relate to light energy?
A: Energy of a photon is directly proportional to its frequency (E = hf, where h is Planck's constant).
