`S_(1)` and `S_(2)` are two coherent sources of frequency `f` each.`(theta _(1)=theta_(2)=0^(@)) V_(sound)=330m//s.`
(i) so that constructive interfence at `'p'`
(ii) so that destructive interfrece at `'p'`

Text Solution

Verified by Experts

For constructive interference
`K Delta x =2npi`
`(2pi)/(lambda)xx2=2npi`
`lambda=(2)/(n) , V=lambdaf rArr V=(2)/(n)f`
`f=(330)/(2)xxn`
For destructive interference
`K Delta x=(2n+1)pi`
`(2pi)/(lambda).2=(2n+1)pi`
`(1)/(lambda)=((2n+1))/(4), f=(V)/(lambda)=(330xx(2n+1))/(4)`
