Name the spectrum of radiations that includes both microwaves and infrared radiation.

The spectrum of radiations that includes both microwaves and infrared radiation is known as the electromagnetic spectrum. The electromagnetic spectrum encompasses a wide range of electromagnetic waves, which are organized according to their wavelengths and frequencies. Microwaves are found in the region of the spectrum with longer wavelengths than infrared radiation.

In this spectrum, the order from longer to shorter wavelengths is as follows:

1. Radio Waves
2. Microwaves
3. Infrared Radiation
4. Visible Light
5. Ultraviolet Radiation
6. X-rays
7. Gamma Rays

Microwaves generally range from about 1 millimeter to 1 meter in wavelength, while infrared radiation covers wavelengths from about 700 nanometers (0.7 micrometers) to 1 millimeter. Together, they play significant roles in various applications, such as communication and thermal imaging.
