Question

Select the correct answer. What can be found by counting the number of troughs per second in a wave diagram? A. Amplitude B. Direction C. Frequency D. Speed E. Wavelength.

Answer 1

Option C is correct. Frequency can be found by counting the number of troughs per second in a wave diagram.

What is the frequency?

Frequency is defined as the number of repetitions of waves occurring in 1 second. It can also be said that Frequency is defined as the number of cycles completed in 1 second.

Frequency is given by the formula as,

$\rm f=\frac{1}{t}$ Hz.

Hence option C is correct. Frequency can be found by counting the number of troughs per second in a wave diagram.
