###### Question details

Little confused about what this question wants by saying frequency range.

The things I believe I know are as follows.

E=h*f(1/2+n)

and k=mw^2=4*m*pi^2*f^2

Could solve the 2nd equation for f, and then plug it into the equation for E to find the energy of the ground state and the first few excited states, but this doesn't help me find a frequency range.
