Project Question: I was doing the "measuring the Speed of 'Light' with a Microwave Oven" experiment, and I was wondering what the independent variables were in the experiment, and if there weren't any, if you could suggest some?
Project Due Date: Thursday December 4th 2014.
Project Status: I am conducting my experiment

Frequency of a microwave oven.

Post by DannySapp1127 »

Would changing the power level of a microwave oven change the frequency of the microwave? Say if I put the microwave on 90%, would the microwave emit a frequency of 90% of 2,450MHz?

DannySapp1127 - The operating frequency of the microwave oven's magnetron is fixed at 2.45 GHz. This is a frequency that has very efficient exciting capability of water molecules, and is also a frequency available in one of the ISM (industrial, scientific, medical) bands, which are internationally reserved for this use, so they don't interfere with other vital radio services. The power level does not change the oscillation frequency of the system.
