What does “Superposition” actually mean in Waves & Sound, and why does it matter for NEET?
When waves overlap, their displacements add algebraically at each point. Constructive and destructive interference are consequences of this linear addition, not permanent destruction of energy.
In simple words: When waves overlap, their displacements add algebraically at each point. Constructive and destructive interference are consequences of this linear addition, not permanent destruction of energy. Getting Superposition clear matters because NEET questions on Waves & Sound usually test this idea directly, not just a formula you memorised.
Key point
Superposition
Common mistake
adding intensities directly before considering phase.
Memory tip
add displacements with phase first, then find intensity.
