The frequency of a wave is 50 Hz. What is its time period?
0.01 s
0.02 s
0.05 s
0.2 s
0.02 s
The time period of a wave is the reciprocal of its frequency. Given a frequency of 50Hz, the time period is calculated as T=f1тАЛ, which yields 0.02s.

If a heartbeat occurs 60 times in 60 seconds (1 Hz), each beat takes 1 second; if it occurs 50 times in a second, each beat must occupy a fraction of that time.
T-F-I: Time equals Frequency's Inverse.
T=f1тАЛ тАФ Relation between time period (T) and frequency (f)
f=T1тАЛ тАФ Relation between frequency (f) and time period (T)
In periodic motion or wave mechanics, frequency (f) represents the number of cycles completed in one second, while time period (T) represents the duration of a single cycle. These two quantities are inversely proportional. The SI unit for frequency is Hertz (Hz) and for time period is seconds (s).
Frequency is defined as cycles per second.
Time period is defined as seconds per cycle.
The product of frequency and time period is always unity (fimesT=1).
Simple relationship allowing quick calculation of wave properties.
Does not apply to non-periodic waves or transients.
AC power supply frequency calculation (e.g., 50Hz in India).
Radio wave and signal processing.
Standard Indian AC power frequency is 50Hz, corresponding to a time period of 0.02s.
Option A (0.01s) results from 1/100, Option C (0.05s) from 1/20, and Option D (0.2s) from 1/5.
B is correct тАФ The time period is the inverse of the frequency, calculated as 501тАЛ=0.02s.
Always verify units before calculating; if frequency is in kHz or MHz, convert to Hz first by multiplying by 103 or 106 respectively.
