In a resonance tube experiment, the first two resonance are observed at length 10.5 cm and 29.5 cm. The third resonance is observed at the length …(cm)

`47.5`

`58.5`

`48.5`

`82.8`

Text Solution

Verified by Experts

The correct Answer is:

`(lamda)/(2)=l_2-l_1=29.5-10.5=19cm`
Third resonance will be observed at
`l_3=l_2+(lamda)/(2)=29.5+19=48.5cm`
