As we learnt in 

Beat Frequency -

\Delta \nu = \left | \nu _{1}-\nu _{2} \right |

module of \left ( \nu _{1} -\nu _{2}\right )

 

- wherein

Where \nu _{1} \: and\: \nu _{2} are frequency of two wave differ slightly  in value of frequency.

 

 Beat frequency = \left | \nu_{2}-\nu_{1} \right |\:=5

\therefore beat period = \frac{1}{\Delta \nu} = 0.2 second
