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.

Explanation:
you're welcome
Concave is not a type of mechanical wave because it doesn’t need a medium for propagation.
