प्रश्न

Two wave pulses travel in opposite directions on a string and approach each other. The shape of one pulse is inverted with respect to the other.

पर्याय

  • The pulses will collide with each other and vanish after collision.

  • The pulses will reflect from each other, i.e., the pulse going towards right will finally move towards left and vice versa.

  • The pulses will pass through each other but their shapes will be modified.

  • The pulses will pass through each other without any change in their shapes.

उत्तर

 The pulses will pass through each other without any change in their shapes.

The pulses continue to retain their identity after they meet, but the moment they meet their wave profile differs from the individual pulse.

You have learnt that a travelling wave in one dimension is represented by a function y= f (x, t)where x and t must appear in the combination x – v t or x + v t, i.e. y = f (x ± v t). Is the converse true? Examine if the following functions for y can possibly represent a travelling wave:

(a) `(x – vt )^2`

(b) `log [(x + vt)/x_0]`

(c) `1/(x + vt)`


For the travelling harmonic wave

y (x, t) = 2.0 cos 2π (10t – 0.0080x + 0.35)

Where x and y are in cm and t in s. Calculate the phase difference between oscillatory motion of two points separated by a distance of `(3λ)/4`.

Assuming the waves travel in straight line, at what distance does the earthquake occur?
