Questions & Step-by-Step Solutions

A sound wave travels at a speed of 340 m/s in air. What is the wavelength of a sound wave with a frequency of 680 Hz?
  • Step 1: Identify the speed of the sound wave, which is given as 340 meters per second (m/s).
  • Step 2: Identify the frequency of the sound wave, which is given as 680 hertz (Hz).
  • Step 3: Use the wave equation, which states that the speed (v) of a wave is equal to its frequency (f) multiplied by its wavelength (λ): v = f * λ.
  • Step 4: Rearrange the wave equation to solve for wavelength (λ): λ = v / f.
  • Step 5: Substitute the values into the equation: λ = 340 m/s / 680 Hz.
  • Step 6: Perform the division: 340 divided by 680 equals 0.5.
  • Step 7: Conclude that the wavelength of the sound wave is 0.5 meters.
  • Wave Equation – The relationship between the speed of a wave (v), its frequency (f), and its wavelength (λ) is given by the equation v = fλ.
  • Wavelength Calculation – To find the wavelength, rearranging the wave equation to λ = v/f is essential.
