Question

The time period of a simple pendulum is 2s. what is its frequency ? what name is given to such a pendulum ?

Answer 1

 Time period (T) = 2s

 Since, T = 1/f ,
 Therefore, 
= f = 1/T
  
Hence, f = 1/2.

Answer 2

Time period(T) = 2 sec

we know from formula..

=) frequency(f) = 1/ T

=) f = 1/2 = 0.5 hertz(Hz) .ans....


The pendulum whose time period is 2 sec is called seconds pendulum..
