NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Easy-Class 12
Consider a diagram showing a sinusoidal wave propagating along a string in the +x direction. If the displacement of the string at x = 0 is represented at two different times t = 0 and t = Δt, which of the following equations correctly describes the wave?
A
y(x,t) = a sin(kx - ωt)
B
y(x,t) = a sin(ωt - kx)
C
y(x,t) = a cos(kx - ωt)
D
y(x,t) = a cos(ωt - kx)
Correct Answer
Option A
Detailed Explanation
The wave equation y(x,t) = a sin(kx - ωt) describes a sinusoidal wave propagating in the +x direction, as mentioned in the NCERT context.
