Answer:
- Time indicates how long it takes for the sound to travel (in seconds)
- Intensity measures how loud the sound is, which is the amplitude (in decibels)
- Frequency refers to how many wave cycles are completed in a second (in Hz)
Step-by-step explanation:
For both the waveform and spectrogram: Time, being the independent variable, is on the x-axis on the graph. Intensity, however, is the dependent variable and goes on the y-axis
Frequency can be found as:
- the lines on the waveform through the interval of time over 1 second
- the inverse of time (f = 1/t) on the spectrogram
