Speed of Sound Formula:
From: | To: |
The speed of sound formula (v = fλ) relates the speed of sound to its frequency and wavelength. This fundamental equation in wave physics allows calculation of how fast sound waves propagate through a medium.
The calculator uses the speed of sound equation:
Where:
Explanation: The speed of sound equals the product of frequency and wavelength. This relationship holds true for all sound waves traveling through a given medium.
Details: Calculating the speed of sound is essential in various applications including acoustics, audio engineering, sonar technology, medical ultrasound, and atmospheric studies.
Tips: Enter frequency in Hertz (Hz) and wavelength in meters (m). Both values must be positive numbers greater than zero for accurate calculation.
Q1: Does the speed of sound change in different mediums?
A: Yes, the speed of sound varies significantly in different materials. It's approximately 343 m/s in air, 1480 m/s in water, and 5120 m/s in iron.
Q2: How does temperature affect the speed of sound?
A: In air, the speed of sound increases with temperature. For every degree Celsius increase, the speed increases by approximately 0.6 m/s.
Q3: What is the typical range of human hearing frequency?
A: Humans typically hear frequencies between 20 Hz and 20,000 Hz, though this range decreases with age and exposure to loud noises.
Q4: Can this formula be used for light waves?
A: Yes, the same formula (v = fλ) applies to all electromagnetic waves, including light, though the speed is constant in vacuum (c = 3×10⁸ m/s).
Q5: Why is wavelength important in sound engineering?
A: Wavelength determines how sound waves interact with objects and spaces, affecting phenomena like diffraction, interference, and room acoustics.
