Wavelength is the physical distance between wave crests. Frequency is how many wave cycles pass a point per second. They are inversely related: longer wavelength means lower frequency.
It is informal but very common and acceptable in most spoken and written contexts, except for the most formal academic or legal writing.
The distance between successive crests of a wave, especially in physics for sound, light, or radio waves.

Think of a WAVE on the sea. The LENGTH from one wave's peak to the next peak is its wavelength. For people, imagine their thoughts as waves; if the 'length' matches, they understand each other.
Conceptual Metaphor
UNDERSTANDING/AGREEMENT IS BEING TUNED TO THE SAME FREQUENCY (from radio technology).
