Answer

We can rank the waves in order of frequency, from largest to smallest: $a \gt d = e \gt b = c$

Work Step by Step

The frequency is the number of cycles per second. Let $t$ be the total time shown on each graph. We can count the number of cycles in each graph to find an expression for the frequency. (a) $f = \frac{5~cycles}{t}$ (b) $f = \frac{2~cycles}{t}$ (c) $f = \frac{2~cycles}{t}$ (d) $f = \frac{4~cycles}{t}$ (e) $f = \frac{4~cycles}{t}$ We can rank the waves in order of frequency, from largest to smallest: $a \gt d = e \gt b = c$
