Question

For a transverse wave propagating in a medium.
Statement $1$: At mean position, $\text{P.E.}$ is maximum.
Statement $2$: At mean position, $\text{K.E}$ is maximum.

• A. Statement $1$ is correct, statement $2$ is incorrect
• B. Statement $1$ is incorrect, statement $2$ is correct
• C. Both statements are correct
• D. Both statements are incorrect

Answer 1

The correct option is B Statement $1$ is incorrect, statement $2$ is correct

At mean position, the particle has maximum velocity.

Here total energy of particle,
$\Rightarrow \text{T.E}=\text{P.E}+\text{K.E}$
If kinetic energy is maximum at mean position, then potential energy will be minimum there.
$\therefore$ Option $\left(b\right)$ is correct.
