1. What is the Frequency of Sound Wave Formula?

The Frequency of Sound Wave formula calculates the number of oscillations per second of a sound wave, which determines its pitch. The formula relates frequency to the velocity and wavelength of the sound wave.

2. How Does the Calculator Work?

The calculator uses the frequency formula:

Where:

• \( f \) — Frequency of Sound Wave (Hz)
• \( C \) — Velocity of Sound Wave (m/s)
• \( \lambda \) — Wavelength of Sound Wave (m)

Explanation: The frequency is calculated by dividing the velocity of the sound wave 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 frequency is essential in acoustics, audio engineering, and telecommunications. It helps determine the pitch of sound, design audio equipment, and analyze wave properties in various media.

4. Using the Calculator

Tips: Enter the velocity of sound wave in meters per second (m/s) and the wavelength in meters (m). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical velocity of sound in air?
A: The velocity of sound in air at room temperature (20°C) is approximately 343 m/s.

Q2: How does temperature affect sound velocity?
A: Sound velocity increases with temperature. In air, it increases by about 0.6 m/s per degree Celsius.

Q3: What is the human hearing frequency range?
A: The typical human hearing range is from 20 Hz to 20,000 Hz (20 kHz).

Q4: How does frequency relate to pitch?
A: Higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches.

Q5: Can this formula be used for all types of waves?
A: Yes, this formula applies to all wave types, including sound waves, light waves, and radio waves, as long as the velocity and wavelength are known.
