The graph shows the amplitude of a passing wave over time in seconds (s). What is the approximate frequency of the wave shown?

Option B. 0.3 Hz

Explanation:

From the question given above, the following data were obtained:

Period (T) = 3 s

Frequency (f) =?

Frequency is related to the period according to the following equation:

Frequency (f) = 1 / period (T)

f = 1/T

With the above formula, we can obtain the frequency wave as illustrated below:

Period (T) = 3 s

Frequency (f) =?

f = 1/T

f = 1/3

f = 0.3 Hz

Therefore, the frequency of the wave is 0.3 Hz

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
