1. What is Frequency of a Wave?

Frequency is the number of complete wave cycles that pass a given point in one second. It is measured in Hertz (Hz) and is a fundamental property of waves, including sound waves, light waves, and electromagnetic waves.

2. How Does the Calculator Work?

The calculator uses the frequency formula:

Where:

• \( f \) — Frequency (Hz)
• \( v \) — Velocity (m/s)
• \( \lambda \) — Wavelength (m)

Explanation: This formula shows the relationship between a wave's frequency, its velocity, and its wavelength. Frequency is inversely proportional to wavelength when velocity is constant.

3. Importance of Frequency Calculation

Details: Calculating frequency is essential in various fields including physics, engineering, telecommunications, and music. It helps determine wave properties, design communication systems, and analyze sound characteristics.

4. Using the Calculator

Tips: Enter velocity in meters per second (m/s) and wavelength in meters (m). Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the unit of frequency?
A: Frequency is measured in Hertz (Hz), where 1 Hz equals one cycle per second.

Q2: How does frequency relate to wavelength?
A: Frequency and wavelength are inversely proportional when wave velocity is constant: higher frequency means shorter wavelength, and vice versa.

Q3: What is the typical frequency range for human hearing?
A: Humans can typically hear frequencies between 20 Hz and 20,000 Hz (20 kHz).

Q4: How does frequency affect wave energy?
A: For electromagnetic waves, higher frequency corresponds to higher energy (E = hf, where h is Planck's constant).

Q5: Can frequency be negative?
A: No, frequency is always a positive value as it represents the number of cycles per second.
