How to Calculate the Speed of a Wave

How can we calculate the speed of a wave given its wavelength and frequency? To calculate the speed of a wave, we can use the formula v = f * λ, where v is the wave speed, f is the frequency, and λ is the wavelength.

Wave speed is an important parameter in understanding the behavior of waves. It represents how fast a wave is moving through a medium, such as air or water. When we know the wavelength and frequency of a wave, we can easily calculate its speed using the formula v = f * λ.

Formula for Calculating Wave Speed:

The formula to calculate the speed of a wave is v = f * λ, where:

  • v = wave speed (in meters per second)
  • f = frequency of the wave (in Hertz)
  • λ = wavelength of the wave (in meters)

Example Calculation:

Let's consider an example where the wavelength of a wave is 45.4 meters and its frequency is 0.64 Hz. To find the speed of this wave, we can plug these values into the formula:

v = 0.64 Hz * 45.4 m = 29.18 m/s

Final Answer: The speed of the wave is approximately 29.18 m/s.
