1- Construct a model of a typical wave

2- Identify the wavelength, amplitude, crest, and trough of a wave

3- Relate wavelength and amplitude to the energy carried by a wave

​Today's Goals:

From the Latin amplitudo which means wide or width

Amplitude

​Old French creste which means the highest part of a helmet

Crest

Old English trog meaning shallow vessel or tray

Trough

Comes from the Latin frequentia which means to assemble in great numbers

​​Frequency

​The highest point of a wave.

​​Crest

​The bottom point of a wave.

Trough

​The distance from the top or bottom of a wave to the resting point/origin. OR half the height of the wave.

Amplitude

​The distance form one point on a wave to the same point on the next wave.

Wavelength

​Label on Page 30

#​1- from Crest to Crest

#2 - from trough to trough

#3 - a point passing through rest point to the same point in the next wave

Finding Wavelength

• All waves have peaks called crests and bottoms called troughs.

• A wavelength measures the distance from crest to crest or trough to trough.

• Amplitude is half the height of a wave.

​

​Remember:

​High Amplitude waves carry High Energy

Low Amplitude waves carry Low Energy

Amplitude

​Long Wavelengths carry Low Energy

Short Wavelengths carry High Energy

​​Wavelength

​Wave energy depends on the following:
