Answer:
A. 125 Hz
Explanation:
Frequency is the inverse of period.
f = 1 / T
Given T = 0.008 seconds:
f = 1 / (0.008 s)
f = 125 Hz
A wave with a period of .008 seconds has the frequency of 125 Hz.
Answer: Option A
Explanation:
The period of wave or the time period of the wave which has the given frequency of 0.008 sec, can be calculated via following steps,
Given that frequency f=0.008 sec
As we know that the frequency[tex]f=\frac{1}{T}[/tex]
The period or the time period becomes, [tex]T=\frac{1}{f}[/tex]
Thereby, substituting the value, we get,
[tex]T=\frac{1}{0.008}=\frac{1000}{8}=125 Hz[/tex]
Therefore, the time period or the period of the wave which has the frequency to be 0.008 sec is found to be 125 Hz.
