Frequency Formula:
| From: | To: |
Sound wave frequency refers to the number of complete wave cycles that pass a given point per second, measured in Hertz (Hz). It determines the pitch of the sound - higher frequencies produce higher pitches, while lower frequencies produce lower pitches.
The calculator uses the frequency formula:
Where:
Explanation: The formula calculates frequency by dividing the wave velocity by its wavelength, showing the inverse relationship between frequency and wavelength.
Details: Frequency calculation is essential in audio engineering, acoustics, telecommunications, and music production. It helps in designing sound systems, analyzing audio signals, and understanding wave behavior in different media.
Tips: Enter 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.
Q1: What is the relationship between frequency and pitch?
A: Frequency directly determines pitch - higher frequencies produce higher-pitched sounds, while lower frequencies produce lower-pitched sounds.
Q2: What is the typical frequency range of human hearing?
A: Humans can typically hear frequencies between 20 Hz and 20,000 Hz (20 kHz), though this range decreases with age.
Q3: How does medium affect sound wave velocity?
A: Sound travels faster in solids than liquids, and faster in liquids than gases. The velocity depends on the density and elasticity of the medium.
Q4: What is the speed of sound in air at room temperature?
A: Approximately 343 meters per second at 20°C (68°F). The speed increases with temperature.
Q5: Can this calculator be used for electromagnetic waves?
A: Yes, the same formula applies to electromagnetic waves, though the velocity would be the speed of light (approximately 3×10⁸ m/s in vacuum).
