Christopher's eats World presents the light spectrum electromagnetic radiation  body everyone this is mister tell him we're here again for another round of chemistry as able to talk about the light spectrum last time we were together we talked about Mike as a way okay we're going to talk about the properties that light has because of the way so sit back get a pencil take some notes start  what is electromagnetic radiation what is the electromagnetic radiation spectrum is the range of electromagnetic radiation links or frequency here's the band or the width of it and electromagnet Spectrum goes all the way from gamma rays am and FM radio waves it's all all of these things in between some people coffee well where's microwave well microwaves are right there in the radar range and you know she have TV FM infrared rays ultraviolet rays X-rays and gamma-rays spacing between there between ultraviolet rays and infrared Rays with happens to be visible light  I noticed that with increasing wavelength we have d increasing frequency increasing wavelength decreasing frequency remember they are in also then that means decreasing wavelength can you shorter means increasing frequency that also means increasing energy what we want to start putting together here now as those wavelength get shorter your frequency is going to get higher  and your energy is going to get high because frequency and energy are make like a Porsche the visible light is a very small portion of the electromatic electromagnetic radiation but is very important part and we need to take note of that and it's the part that play was worthless first because it's easiest to text we can detect visible light with the naked eye we can take him refract it and get the pretty rainbows tell refraction what is your fractional refraction is just the bending of light waves who knows here we can take a prism and we can shoot White computer and Wawa we break it into its 6 colors roygbiv red orange yellow green blue Violet and you know it's been said that Indigo was a color and we believe that that was probably just sure Isaac I'm trying to talk with Steven colors because Kevin was the number of God and Newton was a very religious man and he Turtle become a foot seven colors so you can have the number of God in the rainbow but really when you look at it analyze it I can remember the kid always trying to find indigo next able to find it and because everybody else was just telling me Oh yeah there's seven colors but they're on their only stick that brings it up to can you expect to which is a range of wavelength with no gaps that's what we see when we usually break a sunlight into its colors as a continuous but that's really not what's going to be important to us what's really important to us is a line spectrum and a line spectrum is a range of women with gaps or missing wavelength what spectrum is where you have a an emission spectrum that is just lines and later this is going to be very important for us when we talked about light particles and the work done by Robert Bunsen and Gustav kirkhoff so we want to be sure that we understand a line Spectrum this is what one might look like if I remember this is the line spectrum of hydrogen  no we see these lines there's also lines in the ultraviolet and the infrared arranged as well but this is the visible range of the line Spectrum for elements nice black hairy absorption  Beyond the Lines are emission there's where light is emitted blossoming understand what reflection is the bouncing of light wave off an object  and just kind of like this the light hits the object and the wage that  reflection is the whole reason we seasons  you see because light is reflecting off of sons bouncing off what hit the object and then comes back to your eyes or towards your eyes and then your eyes absorb that interpreted send it to your brain and colors in objects that's all because of light if there's no light if there's no reflected light come back as you cannot see and that's kind of how some of the work coin on today and invisibility like invisibility cloaks and invisi Billy creams and 5 using nanomachines and molecules that reflect light or refract like we can take that light and put you take that light at the molecular level and refracted into a different direction and that life what come back to your eyes then you won't see the object it will appear to you as invisible as you some really cool things out there and you 350 Verizon think I would suggest that you cried to the RSS feed for physics.org and keep up on some of the latest research rely on the news or or magazines to help you out because you're always behind get on the internet get on RSS feed and stay up with the latest information reflection refraction is really interesting things happening  squeaky the color of the sweater because red is reflected and all the other pleasure absorb red and being reflected and red and very low on energy but the colors that are B-Dubs more like blue green and violet real high and energy therefore you're absorbing the high-energy and reflect hello Angie so it's hot color and vice a versa blue or Violet are very cool colors because the hot high energy play being reflected and red and orange and yellow are being absorbed and they are low in the energy okay  get me questions www.msn.com  send an email
