| Question 1 |
The diagram below depicts:
| Sound in waveform | |
| Wind frequency | |
| Line of sight | |
| Compressions on a map |
Question 1 Explanation:
●The generic term waveform means a graphical representation of the shape and form of a signal moving in a gaseous, liquid, or solid medium.
●For sound, the term describes a depiction of the pattern of sound pressure variation (or amplitude) in the time domain
● The temporal frequencies of sound waves are generally expressed in terms of cycles (or kilocycles) per second. The simplest waveform is the sine wave, since it has only one frequency associated with it. The sound waves associated with, say, music, are constantly varying.
●For sound, the term describes a depiction of the pattern of sound pressure variation (or amplitude) in the time domain
