q1 ans false explain

@NishantThakre
It's false......if amplitude is constant....them intensity will also be constant....so loudness will also be constant....
Loudness = 10log(I/I°) decibel

@SanketBiradar
will it not depend on speed
which depends on temperature
and temp. at day and night will be different

@NishantThakre
It's given clear day and. Clear night and temp difference is there is not mentioned so speed will be same

@SanketBiradar
this was given in the solution
only eqn of intensity i know is po^2v/2B
where po is pressure amplitude v is speed
B is bulk modulus
can you show how eqn given in the solution came?
