Describe a simple experiment to illustrate the phenomenon of resonance and explain it.


In following figure shows  A, B, C and D are four pendulums suspended from the same elastic string XY. Lengths of pendulum A and D are equal, while the length of pendulum B is smaller and the pendulum C is longer. The pendulum A is set into vibration.
(a) what is your observation? (b) Give reason for your observation.


Two pendulums C and D are suspended from a wire as shown in the figure give below. Pendulum C is made  to oscullate by displaying it from its mean position. It is seen that D also starts oscillating. 

(i) Name the type of oscillation, C will execute.
(ii) Name the type of oscillation, D will execute.
(iii) If the length of D is made equal to C then what difference will you notice in the oscillations of D ?
(iv) What is the name of the phenomenon when the length of D is made equal to C ?


In fig. shows two tuning forks P and Q of the same frequency mounted on separate sound boxes with their open ends facing each other. The fork A is set into vibration. (i) Describe your observation. (ii) State the principle illustrated by this experiment.


A rifle shot is fired in a valley between two parallel walls. The echo from one wall is heard in 3 s and the echo from the other wall is heard 3 s later. If the velocity of sound at 00c is 330 ms-1 and the temperature in the valley is 100c, calculate the width of the valley. For every 10c rise in temperature, the velocity of sound increase by 0.61 ms-1.
