Or, just use an Ubertooth sniffer. From anywhere near a running microwave you should see it in the 2.4gh range. Its cool to see how some microwaves vary the frequency up and down during a cycle. It looks like a standing wave bouncing back and forth. This also explains the common office phenomena of the wifi dropping every time someone nukes something.

Whether your phone can connect from inside is not a great standard. Your phone's antenna is maybe 1/100,000 the power of a microwave oven magnetron.

Ignoring impedance and assuming the microwave oven is rated at 1kW. 1kilowatt = 60dBm. A typical WiFi receivers works fine at -60dBm = 1 nanowatt. 60-(-60)=120dB, or 12 orders of magnitude. To put that into persepective, a WiFi receiver work with 1/1,000,000,000,000 the power of a 1kW microwave oven.
