Ques 1) A,B, and C are the three particles of a medium whichn are equally seperated along the x-axis. When a sinusodial transverse wave of wavelength lambda propagates along x-axis, the following observations were made :-
(i) A and B have the same speed
(ii) A and C have the smae velocity
Find :-
(a) The min distance b/w A and B
(b) The min distance b/w A and C
Ques 2)The figure represents two sanps of a travellign wave on a string. The first snnap is taken at t= 0 and the secondis taken at t= 0.05 sec. Determine the sepeed of the wave.
Ques 3) If the equation of a disturbing wave at a given instant is y = PQ + (x±c.t) (where y is the displacement at distance x and c is the pulse velocity). The amlitude of the pulse at t=0 is y = 1 1 - x2 and the amplitude of the pulse at t= 2 is y = 1{1 + (x+1) 2 respectively. Then find the pulse velocity.
