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…
