Wave trap filters?

I'm working on a circuit for school and need a little help. Its a wave trap filter/series tuned circuit. How do I figure out the undesirable frequency?
The question is this "This circuit is designed to shunt an interfering signal to the ground and prevent it from entering the receiver. What is the frequency of the signal being blocked".

If it helps this circuit has a 5pF capacitor and a 5H Inductor. Thanks for any help at all.

I doubt it's a 5H inductor, as that would be huge. But the frequency being blocked is likely the resonant frequency of the capacitor and inductor. Do you know how to calculate that. If not Google it.
