Questions & Step-by-Step Solutions

What is the frequency of a sound wave with a wavelength of 0.5 m in air (speed of sound = 343 m/s)?
  • Step 1: Identify the speed of sound in air, which is given as 343 m/s.
  • Step 2: Identify the wavelength of the sound wave, which is given as 0.5 m.
  • Step 3: Use the formula for frequency, which is Frequency (f) = Speed of Sound / Wavelength.
  • Step 4: Substitute the values into the formula: f = 343 m/s / 0.5 m.
  • Step 5: Perform the division: 343 divided by 0.5 equals 686.
  • Step 6: Conclude that the frequency of the sound wave is 686 Hz.
