Nuclear Radiation Vs Electromagnetic Radiation (EVERYTHING YOU NEED TO KNOW MCAT) 

and that's a bad thing? i think that's great dude!

Infrared radiation (IR), sometimes referred to simply as infrared, is a region of the electromagnetic radiation spectrum where wavelengths range from about 700 nanometers (nm) to 1 millimeter (mm). Infrared waves are longer than those of visible light, but shorter than those of radio waves. Correspondingly, the frequencies of IR are higher than those of microwaves, but lower than those of visible light, ranging from about 300 Ghz to 400 THz. Infrared light is invisible to the human eye, although longer infrared waves can be sensed as heat. It does, however, share some characteristics with visible light -- namely, infrared light can be focused, reflected and polarized. Wavelength and frequency Infrared can be subdivided into multiple spectral regions, or bands, based on wavelength; however, there is no uniform definition of each band's exact boundaries. Infrared is commonly separated into near-, mid- and far-infrared. It can also be divided into five categories: near-, short-wavelength, mid-, long-wavelength and far-infrared. The near-IR band contains the range of wavelengths closest to the red end of the visible light spectrum. It is generally considered to consist of wavelengths measuring from 750 nm to 1,300 nm -- or 0.75 to 1.3 microns. Its frequency ranges from about 215 THz to 400 THz. This group consists of the longest wavelengths and shortest frequencies, and it produces the least heat.

Frequencies range from 20 THz to 215 THz. Wavelengths in the far-IR band, which are closest to microwaves, extend from 3,000 nm to 1 mm -- or 3 to 1,000 microns. Frequencies range from 0.3 THz to 20 THz. This group consists of the shortest wavelengths and longest frequencies, and it produces the most heat. Infrared radiation uses Infrared is used in a variety of applications. Among the most well-known are heat sensors, thermal imaging and night vision equipment. In communications and networking, infrared light is used in wired and wireless operations. Remote controls use near-infrared light, transmitted with light-emitting diodes (LEDs), to send focused signals to home-entertainment devices, such as televisions. Infrared light is also used in fiber optic cables to transmit data. Electromagnetic spectrum and visible light illustration Electromagnetic spectrum and visible light In addition, infrared is used extensively in astronomy to observe objects in space that can't be detected in whole or part by the human eye, including molecular clouds, stars, planets and active galaxies. History of infrared radiation technology Infrared was discovered by British astronomer Sir William Herschel in 1800. Herschel knew sunlight could be separated into separate components, a step accomplished by refracting the light through a glass prism. He then measured the temperatures of the different colors that were created. He found the temperature increased as the colors progressed from violet, blue, green, yellow, orange and red light. Herschel then went a step further, measuring the temperature in the portion beyond the red area. There, in the infrared area, he found the temperature to be the highest of all.

Yes, the number of protons changes during beta decay... therefore element changes into a new element... remember it is the number of protons that defines what element the material is... anything with 6 protons in carbon... anything with 7 protons is nitrogen etc... for the MCAT, all you need to know is that electromagnetic radiation and photons are produced when an atoms electron drops to a lower energy state... when an atoms electron drops from a high energy state -> lower energy state, there is energy released in the form of a photon... photons are made through other mechanisms but for the MCAT all you need to know is the electrons dropping to lower energy’s states example..

The way to think about it is that the photons we see is just an arbitrary artifact of evolution.. we have genes that create proteins that can sense “photons in the visible light spectrum”…. Other animals have different genes that create proteins that can “sense” other wavelengths.. so the spectrum we call visible light is somewhat arbitrary and based on the photon spectrums we evolved to be able to sense visually

@@sciencesimplified3890 indeed thanks, but are the other "types' like xray gamma ray micro wave etc all just light also at different wavelengths or colors that our eyes cant see? since the only diff between on color to the next in visible light is wave length ,, i think of the other "types" like x ray and gama ray etc just other colors,,,, but my main question is,, is there any other difference between microwave xray gama ray etc. other than wave length ,, and as the wave length gets smaller ,, the ionization danger is increased? and is heat only in infrared or is it just that the longer wavelengths in general carries more heat as they get bigger? thanks!

@@lusiouse from what I know, the visible spectrum is merely one octave of many resonant octaves within the entire spectrum. Each frequency pulses a unique vibrational tone and each tone resonates with a specific sound and color. Lower slower vibrational pulses, or wavelengths, such as color red, or note A, do contain more heat, heaviness and density than do the faster pulsating oranges yellows, greens and blues. The repeating rainbow pattern of the visible spectrum repeats itself in every octave within the entire spectrum. Just like a piano keyboard. The lower the octave, the deeper and darker the color, sound, feeling tone etc. The higher the octave, the lighter and brighter the color sound or feeling tone. I hope that makes sense. I now see wavelengths or photons as being the frequency of the electromagnetic pulse but I know many still talk in terms of wavelength. Hope that helps

Perhaps I could have clarified further, but the optimal ratio changes the more protons you have, so I meant to say how that ratio rises the more protons you have but you’re right and it also would have been correct to say that stability depends on how many neutrons it has.. under the context of that point in the video both makes sense but sounds like you got the concept!
