A series of pulses of amplitude 022 meter is sent down a, Ask an Expert

Academics

A series of pulses of amplitude 0.22 meter is sent down a string that is attached to a post at one end. The pulses are reflected at the post and travel back along the string without loss of amplitude.

(a) Find the amplitude at a point on the string where two pulses are crossing, if the string is rigidly attached to the post?

(b) Find the amplitude at a point on the string where two pulses are crossing, if the end at which reflection occurs is free to slide up and down?
