Question

Which of the following statements is accurate? A. Compressions and rarefactions occur throughout a transverse wave. B. The wavelength of both transverse and longitudinal waves is measured parallel to the direction of the travel of the wave. C. 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. D. Sound waves passing through the air will do so as transverse waves, which vibrate vertically and still retain their horizontal positions.

Answer 1

Answer;

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

Explanation;

• Longitudinal waves are waves in which the vibration of particles is parallel to the direction of the wave motion. The vibration of particles generates regions known as compressions and rarefactions. Therefore the wavelength is the distance between two successive rarefactions or compressions.

• Transverse waves on the other hand are those waves in which the vibration of particles is perpendicular to the direction of the wave motion. The vibration of particles generates regions of maximum displacement called crests and regions of minimum displacement called troughs. Thus, the wavelength is the distance between two successive crests or troughs.
