NEET Physics Transverse & Longitudinal Waves MCQ Question
Type: MCQ-diagram based-Hard-Class 11
Consider a diagram showing two wave pulses on a string moving towards each other, where one pulse is an upward displacement and the other is a downward displacement. What will be the resulting displacement at the point where they completely overlap?
A
Zero displacement
B
Maximum upward displacement
C
Maximum downward displacement
D
Twice the upward displacement
Correct Answer
Option A
Detailed Explanation
According to the principle of superposition, when two pulses with equal and opposite displacements overlap, they cancel each other out resulting in zero displacement, as described in the NCERT context.
