Waves

HideShow resource information

Waves

Amplitude: The maximum displacement of a

point above the equilibrium point.

1 of 9

Frequency

Frequency: The number of cycles of a wave

that pass a point per second.

2 of 9

Wavelength

Wavelength: The minimum distance between

two adjacent points in a wave that are in phase

with one another.

3 of 9

Wave Speed

 Wave Speed: the change in distance per unit time of a wave  

4 of 9

Phase and Path Difference

Phase Difference: The cycle difference

between the vibrations of two vibrating

particles

Path difference: The difference in distance

from two coherent sources to an interference

fringe

5 of 9

Stationary Waves

Stationary Waves: a standing wave

produced when two progressive waves of the

same frequency, amplitude, and opposite

direction pass through each other.

6 of 9

Coherent

Coherent: two sources of waves that emit

waves with a constant phase difference.

7 of 9

Interference

Interference: When two or more waves

interact with one another

8 of 9

Diffraction

Diffraction: The spreading of waves passing

through a gap or near an edge
