Answer
The range of frequencies is from $~~2.5\times 10^5~Hz~~$ to $~~3.6\times 10^5~Hz$
Work Step by Step
We can find the lowest frequency:
$f = \frac{1}{2\pi~\sqrt{LC}}$
$f = \frac{1}{2\pi~\sqrt{(2.0\times 10^{-3}~H)(200\times 10^{-12}~F)}}$
$f = 2.5\times 10^5~Hz$
We can find the highest frequency:
$f = \frac{1}{2\pi~\sqrt{LC}}$
$f = \frac{1}{2\pi~\sqrt{(2.0\times 10^{-3}~H)(100\times 10^{-12}~F)}}$
$f = 3.6\times 10^5~Hz$
The range of frequencies is from $~~2.5\times 10^5~Hz~~$ to $~~3.6\times 10^5~Hz$
