AIPMT PRELIMS 2002 Physics Wave Equation MCQ Question
Type: MCQ-numerical-Medium-Class 11
A wave travelling in positive X⁻direction with A = 0.2 m velocity = 360 m/s and λ = 60 m, then correct expression for the wave is :-
A
y = 0.2 sin [2π (6t + x/60)]
B
y = 0.2 sin [π (6t + x/60)]
C
y = 0.2 sin [2π (6t − x/60)]
D
y = 0.2 sin [π(6t − x/60)]
Correct Answer
Option C
Detailed Explanation
The wave equation is y = A sin(2π/λ (vt − x)). Substituting the given values, y = 0.2 sin [2π (6t − x/60)].
