The wavelength of two sound waves are 49 cm and 50 cm respectively. If the room temperature is `30^@C` then the number of beats produced by them is approximately (velocity of sound in air `0^@C=332m//s`

Text Solution

Verified by Experts

The correct Answer is:

`y=332sqrt((303)/(273))`
Beat frequency `=f_1-f_2=v((1)/(lamda_1)-(1)/(lamda_2))`
`=332sqrt((303)/(273))((1)/(49)-(1)/(50))xx100cong14`
