Answer:
Explanation:
The probability of fi in a range is given by the integral, whose limits are the range limits, of the square of the wave function y(x).
Example:
let's say range [a,b] with wave function y(x), then

<h2>The intensity of siren is 0.015 W m⁻²</h2>
Explanation:
The intensity of sound is inversely proportional to the square of distance between source and the observer .
Thus Intensity at a distance 25 m is I₁ ∝ I
Similarly the intensity at a distance 50 m is I₂ ∝ II
Dividing II by I , we have
=
=
=
Thus I₂ = x 0.06 = 0.015 W m⁻²
