Which of the following statements is correct concerning transverse and longitudinal waves? A) Transverse waves have vibrations that are parallel to the movement while longitudinal waves have vibrations that are perpendicular to the movement. B) Transverse waves and longitudinal waves both have vibrations that are parallel to the movement. C) Transverse waves have vibrations that are perpendicular to the movement while longitudinal waves have vibrations that are parallel to the movement. D) Transverse waves and longitudinal waves both have vibrations that are perpendicular to the movement.

The correct answer is: **C) Transverse waves have vibrations that are perpendicular to the movement while longitudinal waves have vibrations that are parallel to the movement.** **Explanation:** - **Transverse Waves:** In transverse waves, the particles of the medium vibrate **perpendicular** to the direction in which the wave travels. A common example of a transverse wave is a wave on a string or electromagnetic waves like light. - **Longitudinal Waves:** In longitudinal waves, the particles of the medium vibrate **parallel** to the direction of wave propagation. Sound waves in air are a typical example of longitudinal waves. **Why the Other Options Are Incorrect:** - **A)** This option incorrectly swaps the definitions of transverse and longitudinal waves. - **B)** This option incorrectly states that both types of waves have parallel vibrations. - **D)** This option incorrectly states that both types of waves have perpendicular vibrations. Understanding the distinction between these two types of waves is fundamental in physics, especially in fields like acoustics, optics, and various engineering disciplines. **Final Answer:** C) Transverse waves have vibrations that are perpendicular to the movement while longitudinal waves have vibrations that are parallel to the movement.
