Wave Speed Equation:
From: | To: |
The wave speed equation relates the speed of a wave (v) to its frequency (f) and wavelength (λ). It's a fundamental equation in physics that applies to all types of waves, including sound waves, light waves, and water waves.
The calculator uses the wave speed equation:
Where:
Explanation: The equation shows that wave speed is directly proportional to both frequency and wavelength. Higher frequency or longer wavelength means faster wave propagation.
Details: Calculating wave speed is essential in many fields including acoustics, optics, radio communications, and seismology. It helps in designing communication systems, musical instruments, and understanding wave behavior in different media.
Tips: Enter frequency in Hertz (Hz) and wavelength in meters (m). Both values must be positive numbers. The calculator will compute the wave speed in meters per second (m/s).
Q1: Does this equation work for all types of waves?
A: Yes, the basic equation v = f × λ applies to all wave types, though the actual speed may depend on the medium (e.g., sound travels faster in water than air).
Q2: What are typical wave speed values?
A: Speed of light ≈ 3×10⁸ m/s, sound in air ≈ 343 m/s (at 20°C), ocean waves ≈ 10-30 m/s depending on conditions.
Q3: How does medium affect wave speed?
A: Wave speed changes with medium properties - sound depends on density and elasticity, light depends on refractive index.
Q4: What if I know speed and frequency but need wavelength?
A: The equation can be rearranged: λ = v / f. Similarly, f = v / λ.
Q5: Why do waves change speed when entering new media?
A: Frequency usually stays constant, so wavelength must change to maintain v = f × λ relationship, resulting in speed change.
