Question

Calculate the time period of waves having a frequency of 512 Hz

Answer 1

Answer:

Hello mate,

Here is your answer,

f = 512hz.

c=330m/s.

λ=?

λ=c/v.

=330/512.

= 0.644 m.

Answer 2

Answer:

The time period of waves having a frequency of 512 Hz is, 0.00195s

Explanation:

     

Let f be the frequency of oscillation, N be the number of oscillations completed in time t and T be the time period.

For a pendulum, we have the expression for the time period as,

•         $Time\ period = \frac{1}{frequency}$

        The number of oscillations completed by the pendulum per time is the frequency of oscillation. It can be expressed as,  

        $Frequency = \frac{No\ of\ oscillations}{time\ taken}$

         So as per definition,

         $T = \frac{1}{f}$      ...(1)

• In the question, it is given that,

        $f =512Hz$

        Then using equation(1),

         T = $\frac{1}{512}= 0.00195s$
