Frequency Formula:
From: | To: |
Frequency is the number of complete wave cycles that pass a point in one second, measured in Hertz (Hz). In sound waves, frequency determines the pitch of the sound - higher frequencies produce higher pitches.
The calculator uses the frequency formula:
Where:
Explanation: This formula shows the inverse relationship between wavelength and frequency - as wavelength decreases, frequency increases, assuming constant velocity.
Details: Calculating sound wave frequency is essential in audio engineering, music production, acoustics, telecommunications, and medical imaging applications like ultrasound.
Tips: Enter velocity in meters per second (m/s) and wavelength in meters (m). Both values must be positive numbers greater than zero.
Q1: What is the typical speed of sound in air?
A: At room temperature (20°C), sound travels at approximately 343 m/s in air. This varies with temperature and medium.
Q2: How does frequency relate to pitch?
A: Higher frequencies correspond to higher pitches. The human hearing range is typically 20 Hz to 20,000 Hz.
Q3: Can this formula be used for all wave types?
A: Yes, the formula f = v/λ applies to all wave types including sound, light, and water waves.
Q4: What factors affect sound velocity?
A: Sound velocity depends on the medium (air, water, solid) and temperature. It's faster in denser materials and at higher temperatures.
Q5: How is wavelength measured?
A: Wavelength is the distance between two consecutive points in phase on a wave, typically measured from crest to crest or trough to trough.
