Answer:
2 cm and 6 cm.
Explanation:
The maximum displacement of first square wave pulse is 4 cm and the maximum displacement of second square wave pulse is 2 cm. We need to find a possible displacement of the string when the wave pules overlap.
It could be result in constructive interference or destructive interference.The possible displacement of the string are :
4 cm - 2 cm = 2 cm
4 cm + 2 cm = 6 cm
Hence, the correct options are (A) and (C).
