Speed of Sound Equation:
From: | To: |
The speed of sound equation relates the speed of sound to its frequency and wavelength. It is a fundamental relationship in wave physics that describes how these three properties are interconnected.
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, and medical ultrasound imaging.
Tips: Enter frequency in Hertz (Hz) and wavelength in meters (m). Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the typical speed of sound in air?
A: At 20°C, the speed of sound in air is approximately 343 m/s, but it varies with temperature, humidity, and atmospheric pressure.
Q2: How does medium affect sound speed?
A: Sound travels faster in solids than in liquids, and faster in liquids than in gases due to differences in density and elasticity.
Q3: What is the relationship between frequency and wavelength?
A: For a constant speed, frequency and wavelength are inversely proportional - higher frequency means shorter wavelength, and vice versa.
Q4: Can this equation be used for all types of waves?
A: Yes, the equation v = f × λ applies to all wave types, including electromagnetic waves, though the speed will be different (e.g., speed of light for EM waves).
Q5: How does temperature affect sound speed?
A: Sound speed increases with temperature in gases. In air, speed increases by approximately 0.6 m/s for each degree Celsius increase.
