Question

A periodic transverse wave has an amplitude of 0.20 meter and a wavelength of 3.0 meters. If the frequency of this wave is 12 Hz, what is its speed?

Answer 1

The speed is 36 m/s

Step-by-step explanation:

Speed of any wave is the measure of how fast the wave is propagating or travelling in medium. So, the speed of the wave can be calculated as the product of frequency with wavelength of that wave.

Thus, speed is directly proportional to the frequency and wavelength of a wave.

`Speed = Frequency * wavelength`

Given data:

frequency of the wave is given as 12 Hz

wavelength is given as 3 m

Therefore, the speed will be

Speed = 12 × 3 = 36 m/s

Thus, the speed of the transverse wave is 36 m/s.
