When a wave pulse travelling in a string...

When a wave pulse travelling in a string is reflected from a rigid wall to which string is tied as shown in figure. For this sitution two statements are given below.
(1) The reflected pulse in same orientation of incident pulse due to a phase change of `pi` radians
(2) During relfection the wall exerts a force on string in upward direction

A

only (1) is true

B

Only (2) is true

C

Both are true

D

Both are the wrong

Text Solution

Verified by Experts

The correct Answer is:
D
Reflected pulse will be inverted by a denser medium. The wall exerts force in downwards direction.

A pulse shown here is reflected from the rigid wall A and then from free end B. The shape of the string after these 2 reflection will be

A wave pulse, travelling on a two piece string, gets partically reflected and partically transmitted at the junction, The reflected wave is inverted in shape as compard to the incident one. If the incident wave has speed v and the transmitted wave v'

Two pulses travelling in opposite directions along a string are shown for t=0 in the figure. Plot the shape of the string at t= 1.0, 2.0, 3.0, 4.0 and 5.0s respectively .

A string is tied at two rigid supports . A pulse is generated on the string as shown in figure . Minimum time after which string will regain its shape as shown in figure ( Neglect the time during reflection )

Two pulses travel in mutually opposite directions in a string with a speed of 2.5 cm//s as shown in the figure. Initially the pulses are 10 cm apart. What will be the state of the string after two seconds?

A string that is 10 cm long is fixed at both ends. At t=0, a pulse travelling from left to right at 1cm//s is 4.0 cm from the right end as shown in figure. Determine the next two times when the pulse will be at that point again. State in each case whether the pulse is upright or inverted . .

A series of pulses, each of amplitude 0.150 m , are sent on a string that is attached to a wall at one end. The pulses are reflected at the wall and travel back along the string without loss of amplitude. When two waves are present on the same string. The net displacement of a given point is the sum of the displacement of the individuals waves at the point. What is the net displacement at point on the spring where two pulses am crossing, (a) if the string is rigidly attached to the post? (b) if the end at which reflection occurs is free is slide up and down ?

Two strings 1 and 2 are taut between two fixed supports (as shown in figure) such that the tension in both strings is same. Mass per unit length of 2 is more than that of 1. Explain which string is denser for a transverse travelling wave. .
