Question

the wavelength cannot be measured or calculated using speed times period twice the length of one crest speed divided by frequencythe total length of one crest and troughfrequency times period

Answer 1

frequency times period

Explanation:

We have that the formula that relates the wavelength with the period or frequency is the following

`\begin{gathered} \lambda=(f)/(v) \\ \lambda=(1)/(v\cdot p) \end{gathered}`

By means of the length of the ridge it can also be calculated.

But it cannot be calculated by multiplying the frequency with the period, since they are inverse properties, that is, between them they cancel out.

Since the unit of the period is seconds and the frequency is 1/seconds.

Which means that we cannot calculate the wavelength using frequency times period
