## Homework Statement

A tuning for, fork A, is struck and rings with a frequency of 1000Hz, emitting a power of 4x3.14159 x10^-6

a)what is the intensity of the sound, in w/m^2, that would be measured 1.0 from the tuning fork? assume that the tuning fork approximates a point source?

b) what is the intensity level in dB of this sound?

## Homework Equations

I=P/A

B=10log10(I/Io) Io=10^-12

## The Attempt at a Solution

i have no clue how to work out part a. but i know the solution to part a become the value of I and then you solve for B in part b
