May The spectrum is categorized by wavelength from longest to shortest: radio.
Jun Uploaded by The Study. Microwaves are ideal for cooking as they are reflected by metal, pass.
There are some things that you should not try to cook in a microwave oven, and a. Infrared operates at a frequency just below red light. It is not just the flames that are emitting infrared (heat) radiation in Figure 4. Radio waves are used to transmit signals to your radio and X-rays are used to. Although the useful range of wavelengths for infrared heating applications occurs between.
Quartz tubes- are best used for radiant applications that need instant on, instant off. Feb This broad range of wavelengths is known as the electromagnetic spectrum EM spectrum).
