1. Today’s Agenda
Waves (Part 1) notes
Classwork: Wave Questions

2. Waves (Part 1)
3/17/15

3. Waves Propagation: wave movement
Wave: a vibration in which energy undergoes an oscillation.

4. Waves Period: the time required to complete a cycle.
Frequency: the number of cycles per second.
Medium: A physical environment through which a wave can travel.

5. Waves

6. Waves
Waves transfer energy through the medium not the medium itself

7. Parts of the Wave
Wavelength: the distance between successive identical parts of the wave
Amplitude: the distance between the midpoint and the maximum (or minimum) part of the wave

8. Parts of the Wave
Crest: where the wave is the highest and the disturbance is greatest
Trough: where the wave is the lowest and the disturbance is greatest

9. Parts of the Wave

10. Waves
Mechanical Waves: A wave that requires a medium through which to travel

11. Wave Propagation
Transverse Waves: a wave vibration that propagates at right angles to the direction of the wave
Longitudinal Waves: a wave vibration that propagates in the same direction of the wave

12. Wave Classwork
Answer Question #1-14 on pages 387 and 388.

14. Bellwork
What is frequency?
The number of cycles per second.

15. Frequency, Wavelength and Period
As frequency increases then,
wavelength decreases.
period decreases.
Both are inverse relationships.

16. Superposition Principle
Superposition Principle: when two or more waves pass through the same place at the same time

17. Wave Interference
Interference: the result of the superposition of two or more waves

19. Wave Interference
Constructive Interference: results in a larger amplitude
Destructive Interference: results in a smaller amplitude

22. Standing Waves and Nodes
Standing Wave: A wave in which parts of the wave remain stationary and the wave appears not to be traveling
Node: Any part of a standing wave that remains stationary
