Wave Properties and Graphs

Waves are disturbances that carry energy through space or matter.

​All waves have four properties: amplitude, frequency, wavelength, and speed.

​

Waves

Multiple Select

What are the properties of all waves?

• Speed

• Frequency

• Amplitude

• Wavelength

Maximum distance the particles of the medium carrying a wave move away from their rest position​(Height)​

** In sound waves, amplitude refers to the volume. High amplitude, high volume or loud and vice versa​.

​

Amplitude​

​

The number of complete waves that pass a given point in a second.

** In sound waves, the frequency refers to pitch. Higher frequency, higher pitch and vice versa

​

​​Frequency

​

Distance between two corresponding points on a wave.

Crest-Crest/Trough-Trough

Compression-Compression/Rarefaction-Rarefaction​

​​Wavelength

​How far a wave travels in a given amount of time.

speed = frequency x wavelength​

​​Speed

​Frequency and wavelength are inversely related. As one increases, the other decreases.
