i need answer with in 30 t0 40 minutes

Answer 1

a) both waves are moving in the opposite directions with same amplitudes and peaks are at same height

so they did not get straight line and remaining all are possibles

option c

b) reflection of a mechanical waves between the two ropes is

bigger pulse approaches the flat light rope after interaction flat pulse gets more energy from the thick rope and wave pulse of thick reflects with lower amplitude or peak

option a is the correct answer
