Final answer:
Electromagnetic radiation is connected to the atom through the interaction of atoms with radiant energy. It has been used to study the electronic structure of atoms and identify elements. Electromagnetic radiation is also essential in various technologies.
Step-by-step explanation:
Electromagnetic radiation and the atom are connected through the interaction of atoms with different forms of radiant energy, such as visible light, infrared radiation, ultraviolet light, and x-rays. Scientists have discovered a lot about the structure of the atom by observing this interaction. For example, they have used electromagnetic radiation to identify elements and study the electronic structure of atoms. Electromagnetic radiation is also used in various technologies, such as radio waves, X-ray imaging, and microwave ovens.
