Question
There are three strings RP, PQ and QS as shown. Their mass and lengths are RP = (0.1Kg, 2m), PQ = (0.2 Kg, 3 m), QS = (0.15 Kg, 4 m) respectively. All the strings are under same tension. Wave-1 is incident at P. It is partly reflected (wave-2) and partly transmitted (wave-3). Now wave-3 is incident at Q. It is again partly transmitted (wave-5) and partly reflected (wave-4). Phase difference between wave-1 and wave :
- 2 is
- 4 is zero
- both (a) and (b) are correct
- both (a) and (b) are wrong
The correct answer is: both (a) and (b) are correct

Two trains A and B are moving with speed 20 m/s and 30 m/s respectively in the same direction on the same straight track, with B ahead of A. The engines are at the front ends. The engine of train A blows a long whistle. Assume that the sound of the whistle is composed of components varying in frequency from ƒ1 = 800 Hz to ƒ2 = 1120 Hz, as shown in the figure. The spread in the frequency (highest frequency–lowest frequency) is thus 320 Hz. The speed of sound in still air is 340 m/s. The spread of frequency as observed by the passengers in train B is :–
