Question

question 10 (5 points)listenwhich of the following statements is accurate?a) compressions and rarefactions occur throughout a transverse wave.b) amplitude of longitudinal waves is measured at right angles to the direction of the travel of the wave and represents the maximum distance the molecule has moved from its normal position.c) sound waves passing through the air will do so as transverse waves, which vibrate vertically and still retain their horizontal positions.d) the wavelength of both transverse and longitudinal waves is measured parallel to the direction of the travel of the wave.

Explanation:

• Option A: Compressions/rarefactions are unique to longitudinal waves, not transverse waves (transverse waves have crests/troughs), so A is incorrect.
• Option B: Amplitude of longitudinal waves is measured parallel to the wave's travel direction (not perpendicular), so B is incorrect.
• Option C: Sound waves in air are longitudinal, not transverse, so C is incorrect.
• Option D: Wavelength is defined as the distance between identical points on a wave, which is always parallel to the direction the wave travels for both transverse and longitudinal waves, so D is accurate.

Answer:

D) The wavelength of both transverse and longitudinal waves is measured parallel to the direction of the travel of the wave.
