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:

`lambda//2 = 29.5 - 10.5 = 19 cm`
`3 rd` resonance `= 19 + 29.5 = 48.5 cm`
