Oven vs. Microwave

By Jaxson

Main Difference

The main difference between Oven and Microwave is that the Oven is a thermally insulated chamber used for the heating, baking or drying of a substance and Microwave is a form of electromagnetic radiation.

  • Oven

    An oven is a thermally insulated chamber used for the heating, baking, or drying of a substance, and most commonly used for cooking. Kilns and furnaces are special-purpose ovens used in pottery and metalworking, respectively.

  • Microwave

    Microwaves are a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter; with frequencies between 300 MHz (1 m) and 300 GHz (1 mm). Different sources define different frequency ranges as microwaves; the above broad definition includes both UHF and EHF (millimeter wave) bands. A more common definition in radio engineering is the range between 1 and 100 GHz (wavelengths between 0.3 m and 3 mm). In all cases, microwaves include the entire SHF band (3 to 30 GHz, or 10 to 1 cm) at minimum. Frequencies in the microwave range are often referred to by their IEEE radar band designations: S, C, X, Ku, K, or Ka band, or by similar NATO or EU designations.

    The prefix micro- in microwave is not meant to suggest a wavelength in the micrometer range. Rather, it indicates that microwaves are “small” (having shorter wavelengths), compared to the radio waves used prior to microwave technology. The boundaries between far infrared, terahertz radiation, microwaves, and ultra-high-frequency radio waves are fairly arbitrary and are used variously between different fields of study.

    Microwaves travel by line-of-sight; unlike lower frequency radio waves they do not diffract around hills, follow the earth’s surface as ground waves, or reflect from the ionosphere, so terrestrial microwave communication links are limited by the visual horizon to about 40 miles (64 km). At the high end of the band they are absorbed by gases in the atmosphere, limiting practical communication distances to around a kilometer. Microwaves are widely used in modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication, medical diathermy and cancer treatment, remote sensing, radio astronomy, particle accelerators, spectroscopy, industrial heating, collision avoidance systems, garage door openers and keyless entry systems, and for cooking food in microwave ovens.

  • Oven (noun)

    A chamber used for baking or heating.

  • Microwave (noun)

    An electromagnetic wave with wavelength between that of infrared light and radio waves.

  • Microwave (noun)

    A microwave oven.

  • Microwave (verb)

    To cook (something) in a microwave oven.

  • Microwave (noun)

    an electromagnetic wave with a wavelength in the range 0.001–0.3 m, shorter than that of a normal radio wave but longer than those of infrared radiation. Microwaves are used in radar, in communications, and for heating in microwave ovens and in various industrial processes

    “microwave radiation”

  • Microwave (noun)

    an oven that uses microwaves to cook or heat food

    “a cheesecake was defrosting in the microwave”

  • Microwave (verb)

    cook (food) in a microwave oven

    “he microwaved some steak out of the freezer”
