wave properties review
directions: answer the question about frequency
distance (m)
time (s)
what is the frequency of the wave above?
hz

Explanation:

Step1: Count the number of waves

Looking at the graph from time 0 to 8 seconds, we can count the number of complete wave cycles. By carefully observing the peaks and troughs, we find that there are 16 complete waves in 8 seconds.

Step2: Calculate frequency

The formula for frequency \( f \) is \( f=\frac{\text{number of waves}}{\text{time}} \). Substituting the values, we have \( \text{number of waves} = 16 \) and \( \text{time} = 8 \, \text{s} \). So \( f=\frac{16}{8}=2 \, \text{Hz} \).
