Question

The principle of superposition in wave motion states that ________.

• A. the net displacement is the vector sum of individual displacements
• B. waves interfere with each other and lose energy
• C. waves cannot occupy the same space at the same time
• D. it is applicable to sound waves only
• E. it is applicable to standing waves only

Hint:

Superposition leads to interference patterns (constructive and destructive).

Answer 1

The Correct Option is A

Step 1: Concept
The superposition principle defines how waves combine when they overlap.

Step 2: Meaning
When multiple wave pulses meet at a point, they don't block each other.

Step 3: Analysis
The resulting displacement at any point is simply the sum of the displacements caused by each individual wave.

Step 4: Conclusion
This is mathematically expressed as $\vec{y}_{net} = \vec{y}_1 + \vec{y}_2 + \dots$. Final Answer: (A)
