Wavelength Formula:
| From: | To: |
Wavelength is the distance between consecutive corresponding points of the same phase on a wave, such as the distance between two consecutive crests or troughs. For sound waves, it represents the spatial period of the wave.
The calculator uses the wavelength formula:
Where:
Explanation: The wavelength is calculated by dividing the speed of sound by the frequency of the wave. This relationship shows that higher frequency sounds have shorter wavelengths, while lower frequency sounds have longer wavelengths.
Details: Calculating wavelength is essential in acoustics, audio engineering, and physics. It helps determine how sound waves interact with environments, objects, and other waves, and is crucial for designing acoustic spaces and audio equipment.
Tips: Enter the velocity of sound in m/s and the frequency in Hz. Both values must be positive numbers. The speed of sound in air at room temperature is approximately 343 m/s.
Q1: What is the typical speed of sound in air?
A: The speed of sound in air at 20°C is approximately 343 meters per second. This varies with temperature, humidity, and altitude.
Q2: How does temperature affect sound wavelength?
A: Higher temperatures increase the speed of sound, which increases the wavelength for a given frequency. The relationship is approximately: v = 331 + (0.6 × T) m/s, where T is temperature in Celsius.
Q3: What is the wavelength range of human hearing?
A: For human hearing (20 Hz to 20,000 Hz) in air at room temperature, wavelengths range from about 17 meters (20 Hz) to 1.7 centimeters (20,000 Hz).
Q4: How is wavelength related to sound perception?
A: Wavelength affects how sound waves diffract around obstacles and interact with room dimensions. Low frequency (long wavelength) sounds can bend around objects more easily than high frequency sounds.
Q5: Does wavelength change in different media?
A: Yes, wavelength changes when sound enters a different medium because the speed of sound changes, even though frequency remains constant. For example, sound travels faster in water, resulting in longer wavelengths.
