FM radio stations use radio waves with frequencies from 88.0 to 108 MHz to broadcast their signals. Assuming that the inductance has a value of 4.60 x 10^-7 H, determine the range of capacitance values that are needed so the antenna can pick up all the radio waves broadcasted by FM stations.

_____F (lowest acceptable capacitance)

____F (highest acceptable capacitance)

1. Find Xl (2PI f L)
then find C such that
Xc= 1/2PI*f*C where Xc= Xl

do it at each frequency end.
