Two organ pipes, each closed at one end,...

Two organ pipes, each closed at one end, give 5 beats `s^(-1)` when emitting their fundamental notes. If their lengths are in the ratio `50 : 51, ` their fundamental frequencies are

A

250, 255

B

255, 250

C

260, 265

D

265, 270

Text Solution

Verified by Experts

The correct Answer is:
b
As, `n_(1)/n_(2)=l_(2)/l_(1)=51/50and n_1-n_(2)=5`
On solving, we get
`n_(2)=250, n_(1) = 255`
