Week 17 - PHY: Wave description
Cards in this deck (15)
- 1Define wavesOscillations that carry energy from 1 store to another through a medium or space
- 2What are the 2 types of wavesTranverse and longitudinal
- 3How many peaks pers second is 1MHz1,000,000 Hz
- 4Explain tranverse waves and give 3 examplesDefinition: Waves, in which the particles move perpendicularly to the direction of travel
Examples:
Light waves
Water waves
EM waves - 5Explain longitudinal waves and give 3 examplesDefenition: Waves, in which the particales move parallel to the direction of travel
Examples:
Sound waves
Tsunami waves
Primary Earthquake wave - 6How many peaks pers second is 1GHz1,000,000,000Hz
- 7Identify the difference between tranverse and longitudinal wavesTransverse waves contain particle that vibrate perpendicular to wave motion, while longitudinal waves contain particles that vibrate parallel to wave motion.
- 8Lables this diagramA = Transverse wave
B = Equilibrium/rest position
C = Wavelength
D = Trough
E = Crest
F = Amplitude - 9Label this diagramA = Longitudinal wave
B = Rarefaction
C = Compression
D = Amplitude
E = Displacement of air molecules
F = Wavelength
- 10Define amplitudeThe maximum displacement of a wave's oscillation from its equilibrium position.
- 11Define wavelengthThe distance between one wave crest/trough/compression to the next crest/trough/compression. Measured in meters.
- 12Define wave frontsAn area of a wave where there are many different waves moving together
- 13What is the time and frequency formulaT(s) = 1/f(Hz)
- 14How many peaks pers second is 1KHz1,000Hz
- 15What is the wave, speed equation?V = f * λ
Wave speed = Frequency * Wavelength
(m/s) (Hz) (m)
