According to Mr. Appliance, the life span of the microwave oven is 5-10 years with an average of 8 years. The gas water heater can live 5-13 years with an average of 9 years of use.
Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter; with frequencies between 300 MHz (100 cm) and 300 GHz (0.1 cm). This broad definition includes both UHF and EHF (millimeter waves), and various sources use different boundaries. In all cases, microwave includes the entire SHF band (3 to 30 GHz, or 10 to 1 cm) at minimum, with RF engineering often restricting the range between 1 and 100 GHz (300 and 3 mm). The prefix micro- in microwave is not meant to suggest a wavelength in the micrometer range. It indicates that microwaves are small, compared to waves used in typical radio broadcasting, in that they have shorter wavelengths.
