A source of frequency 10kHz when viberted over than mouth of a closed organ is in unison at 300K. The beats produced when temperature rises by 1K

A

30 Hz

B

`13.33` Hz

C

`16.67` Hz

D

40 Hz

Text Solution

Verified by Experts

The correct Answer is:
C
`f =(1)/(4l) sqrt((gamma RT)/(M))`
Since `Delta T lt lt T`
`implies (df)/(f)= 1/2 (dT)/(T)`
`implies df = 1/2 xx(1)/(300)xx10,000`
`implies df =16.67`
