Question

A wave has a velocity of 24 m/s and a period of 3 s.

Answer 1

Answer:

cannot be determined from the given information

Explanation:

The amplitude of a wave corresponds to the maximum displacement of the wave with respect to its equilibrium position. However, the amplitude of a wave has no relationship neither with its velocity, nor with its period.

On the contrary, velocity and period are related by the following equation:

$v=\lambda \frac{1}{T}$

where v is the velocity, $\lambda$ the wavelength, and T the period of the wave.

Therefore, from the given information we have no way to determine the amplitude of the wave, so the correct answer is

cannot be determined from the given information

Answer 2

The amplitude of the wave doesn't depend on its speed
or frequency.  Knowing both of those doesn't help you
determine the amplitude at all.
