What is a wave?
What is a wave?
Periodic, continuous disturbance consisting of train of pulses
Define transverse wave
Define transverse wave
Particle motion perpendicular to wave propagation direction
What is a crest?
What is a crest?
Highest point; maximum upward displacement from equilibrium
What is a trough?
What is a trough?
Lowest point; maximum downward displacement from equilibrium
Net displacement of particles in a wave
Net displacement of particles in a wave
None; particles return to equilibrium position
Angle between particle & wave motion in transverse wave
Angle between particle & wave motion in transverse wave
90° (perpendicular)
Difference between pulse and wave
Difference between pulse and wave
Pulse is single disturbance; wave is train of pulses
What is equilibrium position?
What is equilibrium position?
Where medium would be if no wave was passing through
Direction of particle motion in transverse wave
Direction of particle motion in transverse wave
Perpendicular (at right angle) to wave direction
Does wave itself have net displacement?
Does wave itself have net displacement?
Yes; energy travels through the medium
