|
|
||||
|---|---|---|---|---|---|
| sound | passage of disturbance through the air or another medium. vibratory energy transmitted by pressure waves in the air or other media. has potential to do work, does not pass though a vacuum.
🗑
|
||||
| wave | disturbance of a medium. particles are temporarily dispalced and then resutrn to their original position.
🗑
|
||||
| longitudinal waves | particles of the medium are displaced in a direction parallel to energy transport (tuning fork)(sound)
🗑
|
||||
| transverse waves | particles of the medium are displaced in a direction perpendicular to the direction of energy transport.
🗑
|
||||
| eleasticity | restoring force. ability of an object to return to its initial position.
🗑
|
||||
| intertia | tendency of a body to remain in motion when in motion and to remain at rest when at rest.
🗑
|
||||
| vibration | movement of an object from one point in space to another point and back again to the first point.
🗑
|
||||
| damping | effect on an objec that reduces the amplitude of oscillation of an object causing the object to come to a stop.
🗑
|
||||
| sinusoidal motion | vibration of pendulum is aperiodic.
🗑
|
||||
| simple harmonic motion | periodic. repeats itself at standard intervals in a specific manner. charcterized by amplitude, period, frequency, phase.
🗑
|
||||
| amplitude | how big the motion is. (measured in dB
🗑
|
||||
| period | how long it takes time it takes to complete one cycle. properties of sine wave
🗑
|
||||
| frequency | number of cycles per unit. measures in hertz properties of sine wave
🗑
|
||||
| phase | determines the starting point on the sine wave. defined in degrees of angle 0-360
🗑
|
||||
| wavelength | distance that a sound wave disturbance travels during one complete cycle.
🗑
|
||||
| velocity | speed of sound. describes how much the wave travels in a certain amount of time
🗑
|
||||
| intantenous amplitude | dispalcement of a sine wave varies with time.
🗑
|
||||
| peak to peak amplitude | from maximum positive peak to the maximum negative peak.
🗑
|
||||
| root mean square amplitude | square root of the average amplitude squared, . 7 time the peak amplitude.
🗑

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.
