Which of the following statements about the ordinary ir spectroscopic regions are true? 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. 3. in general, the energy carried by a photon of ir radiation is greater than the energy carried by a photon of uv radiation. 4. an ir wavelength of 40 microns corresponds to a wavenumber of 25 inverse cm. 5. ordinarily we sense most ir frequencies as colors in the region we call blue.

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.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
