Waves are everywhere. We encounter them every day. We see light waves, hear sound waves, use microwaves, and maybe energy does the wave in a football stadium. In the ocean or a lake, water ripples in waves. Those waves are caused by some disturbance, such as a rock dropped in the water, a moving boat, or larger movements deep at sea.

Simply put, a wave is a disturbance that transfers energy. Waves do not transfer matter but may travel through it. The material a wave travels through to transport energy is called a medium. A medium can be solid, liquid, or gas.

Read Part 1. Jot down notes and drawings that will help you remember the meanings of these words. You can use the sketch/scribble button on the toolbar.

Properties of Waves – Part 1

The wave travels through the medium and displaces matter temporarily, but when the wave has passed, the matter returns to its original position. Waves that transfer energy through matter are called mechanical waves.

Mechanical waves can be transverse or compressional (also called longitudinal). A transverse wave moves matter perpendicular to the direction of the wave. Water waves or waves through a rope are examples of transverse waves. Longitudinal waves displace matter in the same direction that the wave is traveling. Sound waves and earthquake p-waves are examples of longitudinal waves.

A transverse wave has high points called crests and low points called troughs, which represent the displacement (movement) of the particles that a mechanical wave travels through. The distance from the rest position to the crest, or from the rest position to the trough, is called amplitude. Waves carrying more energy have higher amplitudes. The distance from one crest of the wave to the next crest is called wavelength.

Properties of Waves – Part 2

In a longitudinal wave, the movement of particles causes high density in some areas and low density in others.

In the high-density area, called the compression, the particles are close together. In the low-density area, called the rarefaction, the particles are spread out. The amplitude of a longitudinal wave represents the density of the compressions. The wavelength of a longitudinal wave is the distance from the beginning of one compression to the beginning of the next compression.

Visit this website:

In the top left corner, select “Oscillate”.
In the top right corner, select “Loose End”.
In the middle of the page under the wave, select “Slow Motion”.

This animation simulates the motion of one type of wave.

Describe the behavior of the wave.

In the green box under the wave, you will see various sliders.

Move the “Amplitude” slider up to 1.20 cm.
Then move the “Frequency” slider down to 0.20 cm.

Describe how the behavior of the wave differs �as you make these changes.

Then decrease it to 0.70 Hz.
Describe how the behavior of the wave differs as you make these changes.

This animation has been simulating a transverse wave. Transverse waves travel at a perpendicular direction to the direction of the energy transfer. Electromagnetic waves (including visible light, gamma rays, and ultraviolet rays) are examples of transverse waves.

Look around you. Describe how you could use an object in the room to simulate the motion of �this type of wave.

To simulate another type of wave, watch this video:

How does this wave’s motion differ from the transverse wave?

This video represents a longitudinal wave. Longitudinal waves travel in the same direction as the energy transfer. Sound waves are an example of longitudinal waves.

In both types of waves, the frequency is the number of waves that pass a certain point in a given amount of time.

If you had a slinky in front of you to model a �longitudinal wave (like the video), how would �you show a high frequency wave?
