Question

Infrared radiation A) Heat from warm objects, used to detect the location of objects Microwaves B) All the radiation humans can see, ranging from red to violet Ultraviolet light C) Used in radar and to heat food Visible light D) Given off by very hot objects, such as the sun

Answer 1

Answer:

Infrared radiation → A) used to detect the location of objects

Microwaves → D) Used in radar and to heat food

Ultraviolet light → C)Given off by very hot objects, such as the sun  Heat from warm objects

Visible light → B) All the radiation humans can see, ranging from red to violet

Explanation:

Microwaves have magnetic waves with very long lengths, greater than that of infrared light. These waves are produced through vibrations that produce heat, as the microwave is turned on, which allows the food to be heated. These waves are also used to provide communication on some types of devices.

Infrared radiation is a type of non-ionizing radiation that has a low frequency and therefore cannot be visualized, since it is not within a visible electromagnetic spectrum, having a frequency lower than red. It can be used to detect the licalization of objects and does not pose a health risk.

Ultraviolet radiation is extremely harmful to our body. It is characterized by radiation with very small wavelengths, less than 400nm. This type of radiation can be released by the sun and ultraviolet lamps.

Visible light refers to the simplest form of electromagnetic wave and covers all the radiation that our eyes can see, allowing different colors to be seen in the objects we observe according to the reorganization of atoms and molecules.
