[amp_mcq option1=”Infrared region” option2=”Ultraviolet region” option3=”Microwave region” option4=”Visible region” correct=”option1″]<\/p>\n
The correct answer is: A. Infrared region.<\/p>\n
Transition ions absorb light in the infrared region of the electromagnetic spectrum. This is because the energy of the photons in the infrared region is just enough to excite an electron from an inner shell to an outer shell. The electrons in the inner shells are held more tightly to the nucleus than the electrons in the outer shells, so it takes more energy to excite them. The photons in the infrared region have enough energy to do this, but the photons in the visible region do not.<\/p>\n
The infrared region of the electromagnetic spectrum is invisible to the human eye. It has wavelengths that are longer than the wavelengths of visible light, but shorter than the wavelengths of microwaves. The infrared region is used in many different applications, such as remote sensing, night vision, and cooking.<\/p>\n
