Changes in Waves

Essential Question:

How do changes in one part of a wave affect other parts of a wave? (S8P4a,f)


Use the powerpoint to fill in the changes in wave properties notes

Use the PowerPoint to fill in the Changes in Wave Properties Notes


Review parts of a transverse wave

Review: Parts of a Transverse Wave

The amplitude is the peak (greatest) value (either positive or negative) of a wave. The distance from the undisturbed level to the trough or crest.


Changes in waves

Less EnergyTransferred

Largeramplitude= More Energy

More EnergyTransferred


Review parts of a wave

Review: Parts of a Wave

The wavelength is the distance…

between the crests or troughs of two consecutive transverse waves

from compression to compression or rarefaction to rarefaction in a compressional wave


Frequency is the number of wavelengths that pass a point in a given amount of time

Frequency is the number of wavelengths that pass a point in a given amount of time.

Low Frequency

High Frequency


Wavelength and frequency are inversely related

Wavelength and Frequency are inversely related.

If a wave is traveling at the same speed, as the frequency of a wave increases, its wavelength decreases.

The same is true in reverse. As the wavelength of a wave increases, its frequency decreases.


Changes in waves

Long Wavelength

Low Frequency

ShortWavelength

High Frequency


Wavelength frequency and energy

Wavelength, Frequency, and Energy

Shorter Wavelength = Higher Frequency = More Energy

Longer Wavelength = Lower Frequency = Less Energy
