if a wave has a wavelength of 13 meters and a period of 0.005, what's the velocity of the wave?
a. 260 m/s
b. 1,300 m/s
c. 2,600 m/s
d. 1,560 m/s
( dont type any wrong answer on porpuse)

ANSWER:

The velocity of the wavelength is

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,

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

Finding the frequency using time period,

Substituting the  value of time period we have,

Now,

Result:

The velocity of the wave with wavelength 13 meters and time period 0.005seconds is .
