A microwave oven is always switched on, even when it isn't cooking anything. It needs to be in order to recognize your commands and to have a clock. This means that there is a power transformer, and if the transformer laminations are slightly loose, they will vibrate in response to the 60 Hz magnetic field. That means that you will hear a 60 Hz or 120 Hz hum. If your power supply is some other frequency, like 50 Hz, you will hear a 50 Hz or 199 Hz hum. An expensive encapsulated transformer would fix this.

Do wireless keyboards send data to the computer using microwave frequencies?
Whether a wireless computer keyboard uses microwave frequencies for communication with the computer depends on the technology used by the keyboard, and on the definition of microwave frequencies. Wikipedia defines microwave frequencies to be in the 1...30GHz range. Many wireless keyboards operate in the 2.4GHz band, which would make them microwave transmitters (and receivers). Other keyboards use different frequencies, below 1GHz. Those would not be microwave devices, according to this definition. The 802.15.4 standard, for example, lists a 868.0-868.6MHz band (Europe), 902..928MHz (US) and the 2.4GHz (2400...2483.5 MHz) band (worldwide, but subject to regional restrictions).
