5. What is the speed of a wave that has a frequency of 600 Hz and a wavelength of 2 m?

Show the steps you used to solve this problem.

1 answer

To find the speed of a wave, you can use the formula:

\[ \text{speed} = \text{frequency} \times \text{wavelength} \]

Where:

  • Speed (v) is measured in meters per second (m/s),
  • Frequency (f) is measured in hertz (Hz),
  • Wavelength (λ) is measured in meters (m).

Given:

  • Frequency (f) = 600 Hz
  • Wavelength (λ) = 2 m

Steps to solve:

  1. Write down the formula: \[ v = f \times \lambda \]

  2. Substitute the given values into the formula: \[ v = 600 , \text{Hz} \times 2 , \text{m} \]

  3. Calculate the wave speed: \[ v = 1200 , \text{m/s} \]

Conclusion:

The speed of the wave is 1200 m/s.
