|---|---|---|---|---|---|
| wave | a transfer of energy over a distance, in the form of a disturbance
🗑
|
||||
| periodic motion | motion that occurs when the vibration, or oscillation, of an object is repeated in equal time intervals
🗑
|
||||
| transverse vibration | occurs when an object vibrates perpendicular to its axis
🗑
|
||||
| longitudinal vibration | occurs when an object vibrates parallel to its axis
🗑
|
||||
| cycle | one complete vibration or oscillation
🗑
|
||||
| frequency (f) | the number of cycles per second
🗑
|
||||
| hertz (Hz) | the unit of measure of frequency
🗑
|
||||
| period (T) | the time required for one cycle
🗑
|
||||
| amplitude | distance from the equilibrium position to maximum displacement
🗑
|
||||
| equilibrium | the rest position
🗑
|
||||
| crest | high section of a wave
🗑
|
||||
| trough | low section of a wave
🗑
|
||||
| periodic waves | originate from periodic vibrations where the motions are continuous and are repeated in the same time intervals
🗑
|
||||
| pulse | wave that consists of a single disturbance
🗑
|
||||
| wavelength (λ) | distance between successive wave particles that are in phase
🗑
|
||||
| transverse wave | particles in the medium move at right angles to the direction in which the wave travels
🗑
|
||||
| longitudinal wave | particles vibrate parallel to the direction of motion of the wave
🗑
|
||||
| compression | region in a longitudinal wave where the particles are closer together than normal
🗑
|
||||
| rarefaction | region in a longitudinal wave where the particles are farther apart than normal
🗑
|
||||
| universal wave equation | v = f λ
🗑
|
||||
| fixed-end reflection | reflection from a rigid obstacle when a pulse is inverted
🗑
|
||||
| free-end reflection | reflection where the new medium is free to move and there is no inversion
🗑
|
||||
| partial reflection | some of the energy is transmitted into the new medium and some is reflected back into the original medium
🗑
|
||||
| wavefront | the leading edge of a wave
🗑
|
||||
| wave interference | occurs when two or more waves act simultaneously on the same particles of a medium
🗑
|
||||
| destructive interference | occurs when waves diminish one another and the amplitude of the medium is less than it would have been for either of the interfering waves acting alone
🗑
|
||||
| constructive interference | occurs when waves build each other up, resulting in the medium having a larger amplitude
🗑
|
||||
| supercrest | occurs when a crest meets a crest
🗑
|
||||
| supertrough | occurs when a trough meets a trough
🗑
|
||||
| principle of superposition | at any point the resulting amplitude of two interfering waves is the algebraic sum of the displacements of the individuals waves
🗑
|
||||
| resonance | the transfer of energy from one object to another having the same natural frequency
🗑
|
||||
| standing wave | created when waves travelling in opposite directions have the same amplitude and wavelength
🗑
|
||||
| node or nodal point | a point on a wave that remains at rest
🗑
|
||||
| antinode | point midway between the nodes where maximum constructive interference occurs
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
