The change in air pressure when the pure tone is produced is mathematically given as
p(1/2000) =0 mP
<h3>What is the change in air pressure when the pure tone is produced?</h3>This pressure is referred to as the atmospheric pressure, air pressure, or simply pressure. It is the force that is exerted on a surface by the air that is above it due to the gravitational pull that gravity has on the surface. A barometer is an instrument most often used to measure the pressure of the atmosphere. When the pressure in the atmosphere changes, a column of mercury contained inside a glass tube in a barometer will either rise or sink.
Generally, the equation for is pressure mathematically given as
Therefore
p(1/2000) =2sin (4000\pi *1/2000)
p(1/2000) = 2sin (2\pi)
p(1/2000) = 2*0
p(1/2000) =0 mP
In conclusion, the pressure
p(1/2000) =0 mP
