Question

At what distance of 1m from the source intensity of sound is 2 w / m² . What is the power of this wave

Answer 1

Answer:
the power of this wave is 25.12
Step-by-step explanation:
Given I= 2w/m²
r=1 m
We know
Area ,A= 4πr²
Now surface area of the sphere
A=4π×1²
=4π m²
Now ,
The power of the source is
Power= Intensity of sound × Area
P=I×A
=2×4π
=8π
=8×3.14
=25.12
Here is the power of the source is 25.12

Answer 2

25.13274 W (WATT) (Sound Power of the Sound Source)

134.002 dB (Sound Power Level)
