1. What is Wave Frequency?

Wave frequency refers to the number of complete wave cycles that pass a given point per second. It is measured in Hertz (Hz) and is a fundamental property of all types of waves, including sound waves, light waves, and electromagnetic waves.

2. How Does the Calculator Work?

The calculator uses the wave frequency formula:

\[ f = \frac{v}{\lambda} \]

Where:

Explanation: The frequency of a wave is calculated by dividing the wave's velocity by its wavelength. This relationship shows that as wavelength increases, frequency decreases, and vice versa, when velocity remains constant.

3. Importance of Frequency Calculation

Details: Calculating wave frequency is essential in various fields including physics, engineering, telecommunications, and music. It helps determine the properties of sound, light, radio waves, and other electromagnetic radiation.

4. Using the Calculator

Tips: Enter the wave 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 wave period?
A: Frequency is the reciprocal of the period (T). The relationship is: \( f = \frac{1}{T} \), where T is the time for one complete cycle.

Q3: Can this formula be used for all types of waves?
A: Yes, this formula applies to all wave types including mechanical waves (sound, water waves) and electromagnetic waves (light, radio waves).

Q4: What if the wave velocity changes?
A: For electromagnetic waves in a vacuum, velocity is constant (speed of light). For mechanical waves, velocity depends on the medium and may change with frequency.

Q5: How does frequency affect wave energy?
A: For electromagnetic waves, energy is directly proportional to frequency: \( E = hf \), where h is Planck's constant. For sound waves, higher frequencies are perceived as higher pitches.
