Time period of the wave, T=1v=1400=0.0025s

Answer 2

Question :-

What is the time period of the wave having a frequency of 400 Hz ?

Answer :-

$Time \: period \: = \frac{1}{Frequency}$

$T = \frac{1}{400}$

$T = 2.5 \times 10 { }^{ - 3} s$

Extra Information :-

➲ Time period = The time needed by a full wave or travel a full wave is called time period. It is denoted by Capital T .The unit for time period is second.

➲ Frequency = The number of waves produced in a second is called frequency. It is denoted by F .It's unit is Hertz (Hz) .

Some Formulas :

• Frequency =1 / Time period
• Time period = 1 / Frequency
• λ = c / f
