Question

wave properties review
directions: answer the question about frequency.

what is the frequency of the wave above?
______ hz

Explanation:

Step1: Count the number of cycles

From the graph, we observe the wave over a time period of 8 seconds. Let's count the number of complete cycles. By looking at the peaks (or troughs) of the wave, we can see that from \( t = 0 \) to \( t=8 \) seconds, the number of complete cycles \( n \) is 16.

Step2: Calculate the frequency

The formula for frequency \( f \) is \( f=\frac{n}{T} \), where \( n \) is the number of cycles and \( T \) is the time period in seconds. Here, \( n = 16 \) and \( T=8 \) seconds. So, \( f=\frac{16}{8}=2 \) Hz.
