STANDARD Physics Stationary Waves MCQ Question
The stationary wave y = 2a sin kx cos ωt in a stretched string is the result of superposition of y₁ = a sin(kx − ωt) and
y₂ = a cos(kx + ωt)
y₂ = a sin(kx + ωt)
y₂ = a cos(kx − ωt)
y₂ = a sin(kx − ωt)
Correct Answer
Detailed Explanation
The given stationary wave is formed by the superposition of two waves traveling in opposite directions. The correct form for the second wave is y₂ = a sin(kx + ωt).
