many blessings yasser

I am the light beloved

and observe you abusing and hating unto all

you seem very unhappy

this is ok and cool

for ye are loved

so be at peace

Why do you need to lie about people and


say they hate others.


I dont hate anyone.


You are a liar.

Generally, EM radiation, or EMR (the designation 'radiation'


excludes static electric and magnetic and near fields) is


classified by wavelength into radio, microwave, infrared, the


visible region that we perceive as light, ultraviolet, X-rays


and gamma rays.


The behaviour of EMR depends on its wavelength. Higher


frequencies have shorter wavelengths, and lower


frequencies have longer wavelengths. When EMR interacts


with single atoms and molecules, its behaviour depends on


the amount of energy per quantum it carries.



EMR in the visible light region consists of quanta (called


photons) that are at the lower end of the energies that are


capable of causing electronic excitation within molecules,


which lead to changes in the bonding or chemistry of the


molecule. At the lower end of the visible light spectrum,


EMR becomes invisible to humans (infrared) because its


photons no longer have enough individual energy to cause a


lasting molecular change (a change in conformation) in the


visual molecule retinal in the human retina, which change


triggers the sensation of vision.




There exist animals that are sensitive to various types of


infrared, but not by means of quantum-absorption. Infrared


sensing in snakes depends on a kind of natural thermal


imaging, in which tiny packets of cellular water are raised in


temperature by the infrared radiation. EMR in this range


causes molecular vibration and heating effects, which is


how these animals detect it.




Above the range of visible light, ultraviolet light becomes


invisible to humans, mostly because it is absorbed by the


cornea below 360 nanometers and the internal lens below


400. Furthermore, the rods and cones located in the retina


of the human eye cannot detect the very short (below 360


nm) ultraviolet wavelengths, and are in fact damaged by


ultraviolet. Many animals with eyes that do not require


lenses (such as insects and shrimp) are able to detect


ultraviolet, by quantum photon-absorption mechanisms, in


much the same chemical way that humans detect visible


light.


Various sources define visible light as narrowly as 420 to


680[6][7] to as broadly as 380 to 800 nm.[8][9] Under ideal


laboratory conditions, people can see infrared up to at least


1050 nm,[10] children and young adults may perceive


ultraviolet wavelengths down to about 310 to 313 nm.[11]
