Reference no: EM131849110

On a whale-watching expedition, your underwater sound detector picks up a whale sound that has an intensity of 9.0 μW/m2.

Part A

What is the intensity level β of this sound?

β =  dB  

Part B

If your detector tells you that you are 2.3 km from the whale, what is the power of the emitted signal?

P =

Part C

How many whales, emitting sound at the same intensity 9.0 μW/m2 , are needed to produce an intensity level of 100 dB at your location?

N =
