Quite simply, the Microwave Oven uses the Microwave part of the spectrum.
The radio frequency portion of the electromagnetic spectrum uses radio telescopes.

Military action that involves the use of electromagnetic and directed energy to control the electromagnetic spectrum or to attack the enemy is defined as Electronic Warfare (EW). This encompasses tactics and strategies that utilize electromagnetic energy to disrupt, deceive, or deny enemy use of the spectrum, while ensuring friendly forces maintain their own capabilities. EW can include activities such as jamming communications, radar, and other electronic systems, as well as employing directed energy weapons.
The visible light portion of the electromagnetic spectrum would be used to study waves that humans can see. This portion of the spectrum includes colors ranging from red to violet and is the only part of the spectrum visible to the human eye.
Light with a wavelength of 489 nm falls within the blue region of the visible spectrum. It is part of the visible light spectrum. Light with a wavelength of 987 nm falls within the infrared region of the electromagnetic spectrum.

The radio frequency portion of the electromagnetic spectrum uses radio telescopes.
Microwaves because we use them everyday

The electromagnetic spectrum spans from the lowly radio signals (1x104 Hz) that we use for terrestrial broadcasting to gamma rays (1x1021 Hz) from the sun! ===================
Some devices that involve electromagnetic waves that we can't see include microwave ovens (use microwaves), X-ray machines (use X-rays), and radio transmitters (use radio waves). These devices operate on different parts of the electromagnetic spectrum, beyond what is visible to the human eye.
They just use a harsher light in the electromagnetic spectrum.
It is very easy to use!
yes, yes they do :p

Jobs that involve using the electromagnetic spectrum include telecommunications engineers, radio astronomers, radiologists, and remote sensing specialists. These professionals work with various parts of the EM spectrum to communicate, study celestial objects, conduct medical imaging, and gather information about the environment, respectively.
