1.	A sound wave of frequency 1000 Hz and travelling with speed 340 m/s is reflected from the closed end of the tube. At what distance from that end will the adjacent node occur?
Answer» Data : n = 1000 Hz, v = 340 m/s The wavelength of the stationary wave set up in the tube, λ = \(\frac vn\). The distance between successive nodes = \(\frac{λ}2\) = \(\frac{v}{2n}\) = \(\frac{350}{2(1000)}\) = 0.17 m = 17 cm

Answer»

Data : n = 1000 Hz, v = 340 m/s

The wavelength of the stationary wave set up in the tube, λ = \(\frac vn\).

The distance between successive nodes

= \(\frac{λ}2\) = \(\frac{v}{2n}\)

= \(\frac{350}{2(1000)}\) = 0.17 m = 17 cm
