1 Warm up 1/27-28 Copy Question explain your answer
Stick one medium with another, will the wave transfer over? What do you think will happen?

2 Wave interaction/interference
I sense a disturbance...

3

4 Mediums and changes in mediums
A wave is traveling down a medium and hits a boundary. At this point one medium transfers to another

5 Mediums and changes in mediums
the wave travels down medium and hits boundary Boundary is hit and the wave is reflected back and transmitted down the medium The transmitted pulse is upright, the reflected pulse is inverted

6 How waves interact: AKA interference
Constructive Interference : When a wave has the same amplitude position Destructive Interference: When two waves meet and have opposite amplitudes

7 constructive interference
Waves with same amplitude meet Adds together to make a greater amplitude

8 destructive interference
Waves with opposite amplitudes meet Waves meet and create smaller waves Wave keep moving along medium

9 Wave Speed Velocity = Wavelength X Frequency
Wave Speed: speed at which a wave travels Speed of a wave depends on medium it is traveling through Velocity = Wavelength X Frequency

Reflection and Refraction.  When a wave moves from one medium into another (reaches a boundary) ◦ Speed of the wave changes  More dense  slower  less.
