Waves Flashcards
1
Q
Longitudinal
A
Direction of wave travels in is parallel to direction of energy transfer
Sound, Seismic P
2
Q
Transverse
A
Direction of oscillation is perpendicular to direction of energy transfer
EM, seismic S
EM waves travel at the same speed in a vacuum
3
Q
Stationary Wave Formation:
A
Two progressive waves of same frequency and wavelength, similar amplitude, travelling at the same speed in opposite directions superpose
4
Q
Changing Mediums
A
Frequency stays the same
Wavelength and speed change
5
Q
Total Internal Reflection Conditions
A
- Wave is travelling from a higher refractive index to a lower refractive index
- Angle of incidence is greater than the critical angle
6
Q
Diffraction
A
When waves pass through a gap of similar size to their wavelength, they spread out. (change amplitude)
Gap size = Wavelength, more prominent diffraction
