Question

The equation $y=a\sin \frac{2\pi }{\lambda }(vt-x)$ is expression for

• A. stationary wave of single frequency along $x$-axis
• B. a simple harmonic motion
• C. a progressive wave of single frequency along $x$-axis
• D. the resultant of two SHMs of slightly different frequencies

Answer 1

Answer: (C)

The equation of progressive wave propagating in the positive direction of $X$-axis is
$y=a\sin \frac{2\pi }{\lambda }(vt-x)$ or
$y=a\sin (\omega t-kx)$
