Answer:
T = 1.11111111111111111 [repeating] seconds
(T means period)
Explanation:
wave terminology:
period = seconds per wave
frequency = waves per second [hz = in one second]
frequency : f [measured in hertz]
period : T [measured in seconds]
the period is the time it takes for one cycle to occur. If the frequency of the wave is 0.9, that means that 0.9 waves are able to pass in 1 second.
So, we should use the period and frequency relation:
T = [tex]\frac{1}{f}[/tex] f = [tex]\frac{1}{T}[/tex]
So, we should plug in the frequency (0.9) to find the period
T = [tex]\frac{1}{0.9}[/tex]
T = 1.111111
So, the period of this wave (the amount of time it takes for one wave to pass) is 1.1111111 [repeating] seconds
