Awave pulse traveling to the right along a thin cord reaches a discontinuity where the rope becomes thicker and heavier. what is the orientation of the reflected and transmitted pulses?

a) both are inverted

b) the reflected pulse returns inverted while the transmitted pulse is right side up

c) both are right side up

d) the reflected pulse returns right side up while the transmitted pulse is inverted

b) the reflected pulse returns inverted while the transmitted pulse is right side up

Explanation:

A wave pulse traveling to the right along a thin cord reaches a discontinuity where the rope becomes thicker and heavier.

Then, as far as orientation of reflected and transmitted pulses are concerned the reflected pulse returns inverted while the transmitted pulse is right side up.

Hence the correct answer is b.
