Consider a wave generator that produces 27 oscillations per second. The speed of the waves is 22.5 m/s. What is the wavelength of the waves?

Question

a	0.67 m
b	1.92 m
c	0.55 m
d	0.83 m

Answer 1

In this problem, you want to keep in mind the formula that relates wavelength, wave speed, and oscillation per second, more commonly known as Hertz. That formula is: λ= v/f , where λ=wavelength (m), v=velocity (m/s), and f=frequency (number of oscillations/s). Now that we have the formula, we can plug in the velocity (22.5 m/s) and the frequency (27 oscillations per second or 27 Hz). λ= 22.5 m/s / 27 Hz

After plugging that into the calculator, you should get 0.83 m, which is answer choice D.

I hope this was easy to follow and helps you approach future problems like this one!
