I don’t understand your questions can you elaborate
Answer: the statements in 1 and 2 are true of IR spectroscopic region.
1. In general, the IR FUNDAMENTAL region has a longer wavelength region than the region we call the ultraviolet (uv) region.
2. We can sense some of the frequencies of the FUNDAMENTAL region of the IR as heat
Explanation:
IR has energy value between 10^-5eV - 10^-2eVwhile
UV has energy value of 4eV - 300eV
IR has low photon energy and cannot alter atoms and molecules while UV has sufficient energy to iodize atoms therefore UV has a higher energy band.
Infrared light falls just outside the visible spectrum, beyond the edge of what we can see as red.
C) Noble gases
The six noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). Their atomic numbers are, respectively, 2, 10, 18, 36, 54, and 86.
