Question

The particle A , completes 18 oscillations in 4sec. and particle B , completes 21 oscillations in 5sec. Which particle has the highest frequency ?

Answer 1

A completes 18 oscillations in 4 secs

   in one second it can make  = 18/4 =4.5

B completes 21 oscillations in 5 secs

   in one second it can make   = 21/5 =4.2

A completes more oscillations than B

therefore A has more frequency
