Wave and Sound Concepts

What type of wave requires a material medium to propagate?

In which type of wave do particles of the medium move parallel to the direction of wave propagation?

Which of the following examples represents a transverse wave?

What occurs when a wave passes through a medium without transferring matter?

Which statement is true about electromagnetic waves?

How do waves transfer energy in a medium?

Which example best illustrates the concept of a longitudinal wave?

What is the key characteristic that differentiates transverse waves from longitudinal waves?

What kind of waves are sound waves classified as?

When an object is dropped into a pond, what happens to the energy from the impact?

Wave and Sound

Waves transfer energy and momentum through a medium without transferring matter.
All waves are produced by a vibrating source.
Mechanical waves need a medium to travel, whereas electromagnetic waves do not.
Examples of mechanical waves include sound waves and seismic waves.
Examples of electromagnetic waves include light waves and X-rays.

Describing Wave Motion

Wave motion is the transfer of energy through successive disturbances in a medium.
Waves transfer energy without transferring matter.
Examples include dropping a stone in a pond (Figure 7.1) and moving a rope up and down at one end (Figure 7.2).

Transverse and Longitudinal Waves

Transverse waves: Particle displacement is perpendicular to the wave direction. Examples include waves in a vibrating string and light waves.
Longitudinal waves: Particle displacement is parallel to the wave direction. Examples include waves in a slinky and sound waves.
Both transverse and longitudinal waves can be combined in some waves, like water waves.
Longitudinal waves are demonstrated by pushing and pulling on a slinky (Figure 7.4).
Transverse waves can be demonstrated by moving the end of an attached rope or spring up and down (Figure 7.3).
