68-- Which type of wave has a wave perpendicular to the disturbance?1 pointLongitudinaltransverse

The type of wave that has a wave perpendicular to the disturbance is a transverse wave.

Here's a step-by-step explanation:

1. Waves are disturbances that transfer energy from one point to another in space.

2. Waves can be classified into two main types based on the direction of the disturbance relative to the direction of the wave. These are longitudinal waves and transverse waves.

3. In longitudinal waves, the disturbance is in the same direction as the wave. This means that the particles of the medium through which the wave travels move parallel to the direction of the wave. Examples of longitudinal waves are sound waves in air and waves in a slinky.

4. In transverse waves, the disturbance is perpendicular to the direction of the wave. This means that the particles of the medium through which the wave travels move in a direction perpendicular to the direction of the wave. Examples of transverse waves are waves on a string and light waves.

5. Therefore, the type of wave that has a wave perpendicular to the disturbance is a transverse wave.
