1. The problem statement, all variables and given/known data

my question is simple and doesn't really fit the template.

Is wavelength and period of a wave not the same thing?

Wavelength is a physical measure of length, whereas period is a measurement of time.

Defennder is correct, they are different.

They might appear to be the same in drawings of waves, but:

When illustrating the wavelength, the x-axis in the figure would be position or distance (at a fixed time).

When illustrating period, the x-axis would be time (at a fixed position).
