1.1.2 quiz: wave properties\nthe graph shows the amplitude of a passing wave over time in seconds (s).\nwhat is the approximate frequency of the wave shown?

Answer

Explanation:

Step1: Identify the period

From the graph, one complete wave cycle occurs from (t = 0) to (t = 4) seconds. So the period (T=4\ s).

Step2: Use the frequency - period formula

The formula for frequency (f) in terms of period (T) is (f=\frac{1}{T}). Substituting (T = 4\ s) into the formula, we get (f=\frac{1}{4}\ Hz= 0.25\ Hz).

Answer:

(0.25\ Hz)
