Cell ‘phones use frequency bands around 800 to 900 MHz and 1.8 to 1.9GHz.
The wavelength at these frequencies is approximately 35cm and 16cm respectively.
A microwave oven works aa about 2.5GHz, the wavelength of which is about 12cm.
A cell ‘phone’s power output can vary between a few hundred mW (milliwatts) and 3W.
The microwave oven will generate microwave power of up to about 800W.
