Possible answerPossible answer• Wavelength: Wavelength:

the distance the distance between between compressionscompressions

• Amplitude: How Amplitude: How compressed the compressed the medium getsmedium gets

• Frequency: the Frequency: the number of number of compressions compressions that occur per that occur per secondsecond

Wave Behaviors

• Read pg 504-508• Identify the 5 different wave behaviors

and write them on your notes sheet• Define, give examples (draw pictures

to help you) and explanations. Do NOTNOT just copy the book!

Wave Behaviors• Reflection

– When a wave hits a medium it can’t go through, it bounces off that medium

It is the reason we see ourselves in a mirror, see colors and hear an echo.

Wave Behaviors

• Refraction– When a wave hits a new medium it slows

down or speeds up, this causes the wave to bend.

It is the reason things look bigger or out of place when you look at them through water.

Wave Behaviors

• Diffraction– When a wave hits a barrier that has an

opening, the wave spreads out after it goes through the opening

It is the reason you can still hear someone talking in Mr. McWhirter’s classroom, even though there are barriers between us.

Wave Behaviors

• Constructive Interference– When waves meet and the result is a wave

with a higher amplitude

– It is the reason surround sound works. Sound waves meet and create a fuller, richer sound.

– It is also the reason that innertubing behind a boat can be so fun

Wave Behaviors

• Destructive Interference– When waves meet and the result is a wave

with a lower amplitude

It is the reason a stereo may be loud in one part of the room, but quiet in another part. Sound waves meet and create a quieter sound

Noise canceling head phones also work because of this behavior of wave
