Q6 of 97 Page 322

A cork floating in a calm pond executes simple harmonic motion of frequency v when a wave generated by a boat passes by it. The frequency of the wave is

The boat transmits the same wave without any change in the frequency to cause the cork to


execute SHM with same frequency, thought the amplitude may differ due to distance separation


between them.

Which of the following is a mechanical wave?

 7

Two string A and B, made of same material, are stretched by same tension. The radius of string A is double of the radius of B. A transverse wave travels on A with speed υA and on B with speed υB. The ratio υA/υB is

 8

Both the strings, shown in figure (15.Q1), are made of same material and have same cross section. The pulleys are light. The wave speed of a transverse wave in the string AB is υ1 and in CD it is υ2. Then υ1/υ2 is
