What is a longitudinal wave in physics?
Understand the Problem
The question is asking for the definition and explanation of a longitudinal wave in the context of physics. It seeks to clarify what characterizes this type of wave and how it differs from other types of waves, such as transverse waves.
Answer
A longitudinal wave is a wave where the medium's particles move parallel to the wave's direction.
A longitudinal wave is a type of wave where the particles of the medium move in a direction parallel to the wave's propagation. Examples include sound waves traveling through air, where particles compress and expand in the direction the wave moves.
Answer for screen readers
A longitudinal wave is a type of wave where the particles of the medium move in a direction parallel to the wave's propagation. Examples include sound waves traveling through air, where particles compress and expand in the direction the wave moves.
More Information
In contrast to longitudinal waves, transverse waves have particles that move perpendicular to the wave's direction. Sound waves are a common example of longitudinal waves.
Tips
A common mistake is confusing longitudinal waves with transverse waves, where the motion of the medium is perpendicular to the wave direction.
