QUESTION:
Problem 18P
If the amplitude of a sound wave is tripled, (a) by what factor will the intensity increase? (b) By how many dB will the sound level increase?
ANSWER:
Step 1 of 2
As intensity is directly proportional to the square of the amplitude;
Here is the intensity and is the amplitude.
So by tripling the amplitude intensity will increase by times the initial value.
Therefore tripling the amplitude intensity will increase by times the initial value.
