Asound wave has a velocity of 350 meters/second and a frequency of 430 hertz. what is it's wavelength?
a. 0.01
b. 0.60
c. 0.81
d. 0.08

Velocity of the sound wave = 350 meters/second
Frequency of the sound wave = 430 Hertz
Then
Wavelength = speed / frequency
                    = 350/430
                    = 0.81
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the third option or option "C". I hope that this is the answer that has actually come to your desired help.
