1. What is Wave Frequency?

Wave frequency (f) is the number of wave cycles that pass a fixed point in unit time, measured in Hertz (Hz). It's a fundamental property of waves that determines many of their characteristics.

2. How Does the Calculator Work?

The calculator uses the wave frequency equation:

Where:

• \( f \) — Frequency in Hertz (Hz)
• \( V \) — Wave velocity in meters per second (m/s)
• \( \lambda \) — Wavelength in meters (m)

Explanation: The equation shows that frequency is directly proportional to velocity and inversely proportional to wavelength.

3. Importance of Frequency Calculation

Details: Calculating wave frequency is essential in physics, engineering, acoustics, and telecommunications for understanding wave behavior, designing systems, and solving practical problems.

4. Using the Calculator

Tips: Enter velocity in m/s and wavelength in meters. Both values must be positive numbers. The calculator will compute the frequency in Hertz.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between frequency and period?
A: Frequency measures cycles per second, while period is the time for one complete cycle. They're inversely related (f = 1/T).

Q2: How does frequency relate to wave energy?
A: For electromagnetic waves, energy is directly proportional to frequency (E = hf, where h is Planck's constant).

Q3: What are typical frequency ranges?
A: Sound waves: 20Hz-20kHz (human hearing), Radio waves: 3kHz-300GHz, Visible light: ~400-800THz.

Q4: Does frequency change when a wave moves between media?
A: Frequency remains constant, but velocity and wavelength change to maintain f = V/λ.

Q5: How is frequency measured experimentally?
A: Using oscilloscopes for electrical signals, frequency counters, or by measuring period and calculating f = 1/T.
