### Notes pb lab 05 making waves

1. 1. Making Waves
2. 2. Key Objectives:Key Objectives: Investigate and understand the nature anddescribe the characteristics of two typesof waves.– Transverse Waves– Longitudinal Waveshttp://www.youtube.com/watch?v=27a26e2CnuM Model, label and draw diagrams of each.
3. 3. Key TermsKey Terms Wave Wavelength Frequency Transverse Wave Amplitude Crest Trough Longitudinal Wave Compression Rarefaction
4. 4. Wave A disturbance thatcarries energy awayfrom its sourcethrough matter orempty space. Three categories:– Mechanical Waves– ElectromagneticWaves– Matter Waves
5. 5. Transverse Wave A type of wave thatcan travel throughboth a medium orempty space. The energy movesperpendicular to thedirection of thewave.– Light– Water
6. 6. Longitudinal WaveA type of wave thatmust travel througha medium.The energy movesparallel to thedirection of the wave– Sound
7. 7. All Waves
8. 8. WavelengthThe length of thewave.Measured from twoidentical points on awave
9. 9. Frequency The number ofwaves counted in aspecific period oftime. (per second)– Measured in Hertz(Hz)
10. 10. Amplitude In a transverse wave:The height or depth ordifference from therest point to the peakof a wave In a longitudinal wave:The density/thicknessof the compression
11. 11. The Transverse Wave http://www.youtube.com/watch?v=UHcse1jJAto
12. 12. CrestThe top point of atransverse wave
13. 13. TroughThe lowestpoint of atransversewave
