Question

Vibrating tuning fork of frequency n is placed near the open end of a long cylindrical tube. The tube has a side opening and is fitted with a movable reflecting piston. As the piston is moved through 8.75 cm, the intensity of sound changes from a maximum to minimum. If the speed of sound is 350 m/s. Then n is

500 Hz
1000 Hz
2000 Hz
4000 Hz

The correct answer is: 1000 Hz

When the piston is moved through a distance of 8.75cm, the path difference produced is $2 cross times 8.75 c m equals 17.5 c m$ . This must be equal to $fraction numerator lambda over denominator 2 end fraction$ for maximum to change to minimum. \ $fraction numerator lambda over denominator 2 end fraction equals 17.5$ cm Þ $lambda equals 35 c m equals 0.35 m$
So, $v equals n lambda$ Þ $n equals fraction numerator v over denominator lambda end fraction equals fraction numerator 350 over denominator 0.35 end fraction equals 1000 H z$

A wire of $9.8 cross times 1 0 to the power of negative 3 end exponent k g m to the power of negative 1 end exponent$ passes over a frictionless light pulley fixed on the top of a frictionless inclined plane which makes an angle of 30° with the horizontal. Masses m and M are tied at the two ends of wire such that m rests on the plane and M hangs freely vertically downwards. The entire system is in equilibrium and a transverse wave propagates along the wire with a velocity of 100 ms^–1. Chose the correct option
