Question 4 • TX-Physics B-CR

What is the main difference between a longitudinal wave and a transverse wave?

Answer
A
A longitudinal wave always travels faster than a transverse wave.
B
A longitudinal wave does not need a medium to travel through.
C
A transverse wave is made of particles that move perpendicular to the motion of the wave.
D
A transverse wave always carries more energy so that it can travel through empty space.

Explanation

In a transverse wave, particles vibrate perpendicular to the direction the wave travels. In a longitudinal wave, particles vibrate parallel to the wave’s direction of travel. Therefore, choice C correctly describes the key difference; wave speed and energy do not define the difference.
