E. Wave Front – locus of adjacent points on a wave which are in phase
Top View Ex) Distance between arrows = .90 cm
Wavelength of wave?
λ = .30 cm
III. Periodic Wave Phenomena
Interference – effect produced by two waves passing simultaneously through a region
1. Superposition – when waves overlap, the resultant displacement is the algebraic sum of the individual displacements of each wave
a) Constructive Interference
1)
2)
Amplitude?
2A
3)
Waves reemerge as separate waves
b) Destructive Interference
1.
2. At moment of overlap, amplitudes cancel (for a moment)
3. Waves reemerge as separate waves
(1) vibrate up and down (2) vibrate left and right (3) vibrate into and out of the page (4) remain stationary
(4) remain stationary
