Explanation:13/ 0.005=2,600.

Answer 2

ANSWER:

The velocity of the wavelength is $2600 \mathrm{m} / \mathrm{s}$

Explanation:

Given:

The wavelength of the wave= 13 meters

Time period of the wave=0.005seconds

To find:

velocity of the wave=?

Solution:

The velocity of the wave is defined as the product of frequency and wavelength.

Mathematically,

$v=f \lambda$

Where f is the frequency and λis the wavelength of the wave.

Finding the frequency using time period,

$f=\frac{1}{T}$

Substituting the  value of time period we have,

$f=\frac{1}{0.005}$

$f=200 \mathrm{Hz}$

Now,

$v=f \lambda$

$v=200 \times 13$

$v=2600 \mathrm{m} / \mathrm{s}$

Result:

The velocity of the wave with wavelength 13 meters and time period 0.005seconds is $2600 \mathrm{m} / \mathrm{s}$.
