Incorrect Wave Statement – Rankers Physics

Uncategorized: Practice Problem & Solution

For a transverse wave on a string, the displacement is described by $y = Asin(kx - omega t)$. Then which of the following statement is incorrect?
Wave is moving along $+x$ axis.
The shape of the string at $t = 0$ is a sine wave.
Wave is moving along $+y$ axis.
Wavelength of the wave is $frac{2pi}{k}$.

Solution Explained:

To solve this problem, we apply the core principles of Uncategorized. Understanding the underlying formula is key to arriving at the correct answer below:

The expression represents a wave propagating along the positive $x$-direction because of the term $(kx - omega t)$. The medium particles oscillate along the $y$-axis.
