# Question 0d546

Oct 14, 2017

The relationship is v=λ*f.

#### Explanation:

The period, T, which has dimension of time (typically seconds), is the reciprocal of frequency, f, which has dimension of "time^-1. So T=1/f. Therefore,

v=λ*f#.

A note about Hz. The units "cycles/second or cps" was previously used. It might help understanding to think of it that way.

I hope this helps,
