Question

Select the correct answer.
What will change the velocity of a periodic wave?
O A. changing the wavelength of the wave
O B. changing the medium of the wave
OC. changing the frequency of the wave
Help

Answer 1

The wave speed completely depends on the characteristics and properties of the medium  . . . physical properties for mechanical waves, electrical properties for electromagnedtic waves.

So if you want to change the speed of a wave, you have to change the medium . . . shoot it through some different kind of stuff. (B)

Answer 2

The correct answer is B
