There are two springs, one delicate and another stiffer one. Which spring will have a greater frequency of oscillation for a given load ?

Explanation

We have,.v = 1/(2pi)sqrt(k)/(m) = 1/(2pi)sqrt g/l. So, when a hard spring is loaded with mass m. The extension I will be lesser w.r.t delicate one. So frequency of the oscillation of the hard spring will be more and if time period is asked it will be lesser.
