A sound wave of pressure amplitude 14 pascal propagates through the air medium. The normal pressure of air is `1.0xx10^(5)N//m^(2)` the difference between maximum and minimum pressure in the medium is
A
`5xx10^(5)N//m^(2)`
B
`10xx10^(5)N//m^(2)`
C
`10N//m^(2)`
D
None of these
Text Solution
Verified by Experts
The correct Answer is:
C
The minimum pressure is `p_(min)=(10^(5)-5)N//m^(2)` The maximum pressure id `p_(max)=(10^(5)+5)N//m^(2)` `therefore" "Delta pi=p_(max)-p_(min)=10N//m^(2)`
