1.  More Waves

2. Waves Waves are the means by which energy is transferred from one point to another There are two types of waves: transverse and longitudinal Ex. Rope Ex. Slinky

3.  Medium- what the wave travels through  Ex. Water, spring, string, air Longitudinal waves- sound waves, seismic waves or pressure waves Transverse waves- electromagnetic waves

4. Waves Parts of a Wave the height of the wave Distance between two points Frequency- the number wave that pass a point in a second

5. Waves The Wave Equations

6. Waves Reflection: bounce off a surface Refraction: bend through an object Diffraction: waves wrapping around an edge Wave Movement

7. Waves Resonance: vibrations caused by waves Polarization: filters block out certain wavelengths and allow only certain waves through Wave Movement

8. Standing Waves  Between two barriers- node on each end. At the nodes, the wave changes direction.

9. n= # of antinodes v=f λ v= λ 2L  f=(nv)/2L  Standing wave where 1 λ =2L

10. Interference  Interference when two or more waves meet  Constructive interference- waves add get bigger  Destructive interference- waves get smaller and cancel out

11. λ short =c/f largest
