Question 968750: In desperate need of help with this one,
A sound wave has frequency 50 Hz (i.e. it has wavelength (period) = 0.02 seconds). Within each beat, the highest sound intensity is 100 decibel (dB) and the lowest intensity is 60 dB. Supposing that t = 0 corresponds to the low intensity, write down a trigonometric function that describes this sound wave. Sketch the sound wave over two periods. Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! A sound wave has frequency 50 Hz (i.e. it has wavelength (period) = 0.02 seconds). Within each beat, the highest sound intensity is 100 decibel (dB) and the lowest intensity is 60 dB. Supposing that t = 0 corresponds to the low intensity, write down a trigonometric function that describes this sound wave. Sketch the sound wave over two periods.
----------------
Wavelength is distance, not time.
Period = 0.02 seconds
------
S(t) = 20*sin(x*2pi/0.02) + 80
Add the phase shift
