Jenny, there's been a mistake, you definitely *don't need* a 500 Farad capacitor unless you plan on frying your in-laws Frankenstein style. With a 500 Farad capacitor, you can orbit Arnold Schwarzenegger and it would be the size of a small cow. It makes no sense in the context of an oscillator circuit driving an LED, be it for 40 Mhz or 40 Hz. I'll assume there's another typo and you meant 40 Hz. In that case my gut feeling says you need 40 pico or micro at most depending on the context of the circuit. For 40 Mhz you typically need orders of magnitude less.
