NEET Physics Wave Motion MCQ Question
Type: MCQ-diagram based-Hard-Class 11
Consider a diagram showing two pulses on a string, one traveling to the right with a positive displacement and the other traveling to the left with a negative displacement. When these pulses overlap perfectly, what will be the displacement at the point of overlap?
A
Zero displacement due to destructive interference
B
Double the displacement due to constructive interference
C
Displacement remains unchanged
D
Displacement is the average of the two
Correct Answer
Option A
Detailed Explanation
When two pulses with equal and opposite displacements overlap, they undergo destructive interference, resulting in zero displacement at the point of overlap, as described in the NCERT context about wave superposition.
