Question
An under water swimmer sends a sound signal to the surface. It is produces 5 beats/sec when compared with fundamental tone of a pipe of 20 cm length closed at one end what is wavelength of sound in water.
(take Vwater = 1500 m/sec Vair - 360m/sec)
(take Vwater = 1500 m/sec Vair - 360m/sec)
Options
A.3.3 m or 3.37 m
B.4.4 m or 4.47 m
C.2.5 m or 2.7 m
D.1m or 1.7 m
