WavesAll kinds of waves…

Waves

• Wave characteristics are the same on matter what type of wave we are dealing with.

Wave Types

• Standing wave, Traveling wave, Compression wave

Waves

• Crest, trough, wavelength, frequency, amplitude, wave speed, node are all characteristics that need to be identified.

Anatomy

Crest

Trough

Amplitude

Wavelength

Node

Wave height

Compression Waves

Mechanical Waves

• Must travel through a medium.

Electromagnetic Waves

• No medium

• (Not even an extra-large)

•

Electromagnetic Waves

• Light will travel through a vacuum

• Sound will not go through a vacuum

Electromagnetic Waves

???

• What is happening with frequency?

• What is happening with wavelength?

• What is happening with energy?

Energy

• Increases with amplitude

Amplitude

• Light: Brightness

• Sound: Volume

Frequency

• Light: Color

• Sound: Pitch

…

• There are days…

• I wish I could increase the amplitude of my students…

• Just sayin’…
