CHAPTER 14.2 NOTESWave Behavior

Definitions:

Incident wave – the incoming part of the wave

(The incident wave comes from the source of the wave)

Reflected wave – the part of the wave that bounces off a surface

Examples:

Example 2

Waves striking a boundary

Mechanical waves striking more dense medium will speed up

Their wavelength will decrease and their frequency will increase

Anything reflected will be inverted (upside down)

Waves striking a boundary

Mechanical waves striking a less dense medium will slow down

Their wavelength will increase and their frequencies will decrease

Anything reflected will be erect (upright)

Destructive interference

Destructive Interference 2

Constructive interference

Other stuff:

Nodes – points of minimal movement

Antinodes – points of maximal movement

Reflection – waves bouncing off

Refraction – waves bending

Refraction #2

Refraction #3

Diffraction – waves bending around the edge and expanding

Diffraction #2

That was fun…
