Question

The horizontal speed of the wave is:

विकल्प

• $$ 1 \mathrm{~ms}^{-1}$$

• $$ 2 \mathrm{~ms}^{-1}$$

• $$ 4 \mathrm{~ms}^{-1}$$

• $$ 0.5 \mathrm{~ms}^{-1}$$

Answer 1

$$ \mathbf2 \mathbf{~ms}^{-1}$$

Explanation:

The wavelength of the wave is 4 m and its time period is 2 s.

\[ v=\frac{\lambda}{T} \]

\[=\frac{4}{2}\]

= $$ 2 \mathrm{~ms}^{-1}$$
