Choose the correct option:
Which of the following equations represents a wave travelling along Y-axis?
विकल्प
x = A sin(ky – ωt)
y = A sin(kx – ωt)
y = A sin(ky) cos(ωt)
y = A cos(ky) sin(ωt)
उत्तर
x = A sin(ky – ωt)
Explanation:
The direction of the displacement of a wave is perpendicular to the wave's motion direction in transverse waves. When a transverse wave is moving in a y-direction, then the displacement of the wave will be in the x-direction, and if the wave which is travelling along the x-axis, its displacement will be towards the y-axis.
The equation for the wave travelling along the y-axis is x = A sin(ky – ωt)
