Questions & Step-by-Step Solutions

A sound wave travels through air at a speed of 340 m/s. What is the wavelength of a sound wave with a frequency of 1700 Hz? (2022)
  • Step 1: Identify the speed of the sound wave, which is given as 340 m/s.
  • Step 2: Identify the frequency of the sound wave, which is given as 1700 Hz.
  • Step 3: Use the formula for wavelength, which is λ = v / f, where λ is the wavelength, v is the speed, and f is the frequency.
  • Step 4: Substitute the values into the formula: λ = 340 m/s / 1700 Hz.
  • Step 5: Perform the division: 340 divided by 1700 equals 0.2.
  • Step 6: Conclude that the wavelength of the sound wave is 0.2 meters.
  • Wave Properties – Understanding the relationship between speed, frequency, and wavelength of sound waves.
  • Formula Application – Applying the formula λ = v/f correctly to calculate wavelength.
