A wave completes 75 cycles in 25 s. What is its period ?
f = 75/25 = 3Hz
period = 1/f = 3 seconds
To find the period of the wave, we can use the formula:
Period (T) = Total time (t) / Number of cycles (N)
The given information states that the wave completes 75 cycles in a total time of 25 seconds. Therefore, we can substitute these values in the formula:
T = 25 s / 75
To simplify the calculation, we can divide both the numerator and the denominator by 25:
T = 1 s / 3
Hence, the period of the wave is 1/3 second.
To find the period of a wave, we need to use the formula:
Period = Time / Number of Cycles
Given that the wave completes 75 cycles in 25 seconds, we can plug these values into the formula:
Period = 25 s / 75 cycles
Calculating this, we get:
Period = 0.3333... s
So, the period of the wave is approximately 0.333 seconds.
