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.
