Question
A narrow tube is bent in the form of a circle of radius R, as shown in the figure. Two small holes S and D are made in the tube at the positions right angle to each other. A source placed at S generates a wave of intensity I0 which is equally divided into two parts: one part travels along the longer path, while the other travels along the shorter path. Both the part waves meet at the point D where a detector is placed
If a maxima is formed at a detector then, the magnitude of wavelength of the wave produced is given by
- pR
- pR/2
- pR/4
- all of these
The correct answer is: all of these

Superposition of waves results in maximum and minimum of intensities such as in case of standing waves. This phenomenon is called as interference. Another type of superposition result in interference in time which is called as beats. In this case waves are analyzed at a fixed point as a function of time. If the two waves are of nearby same frequency are superimposed, at a particular point, intensity of combined waves gives a periodic peak and fall. This phenomenon is beats. If w1 and w2 are the frequencies of two waves then by superimposed y = y1 + y2 , we get at x = 0, 
Thus amplitude frequency is small and fluctuates slowly. A beat i.e., a maximum of intensity occurs, also intensity depends on square of amplitude. The beat frequency is given by 
Number of beats per second is called as beat frequency. A normal ear can detect only upto 10 Hz of frequency because of persistence of ear The frequency of beats produced in air when two sources of sound are activated, one emitting wavelength 32 cm, other 32.2 cm is

A traveling wave on stretched string can be understood by the function y = f(x -vt). Here v is the wave speed ‘x’ is co-ordinate of point and ‘y’ is its instantaneous displacement. To describe the wave completely, we must specify the function f. If the wave moves in negative x-direction y (x, t) = f(x + vt) and if it moves in positive x-direction y (x, t) = f(x - vt). The general relation for a traveling wave must satisfy the relation
