Radio waves

-frequency and wave length range of your wave:

Radio wave’s frequencies vary from 300 GHz to 3 kHz. Their wavelength varies from 1 millimeter to 100 kilometers.

-placement in the EM spectrum

Radio waves have the longest wavelengths and are located on the far left of the spectrum.

– energy associated with your wave and the properties based f, wavelength, and E!

Energy associated with my wave in biomass energy because burning wood also produces heat and light and the decry of heavy isotopes that cause radiation and radio waves. Not sure about the frequencies, wavelengths, and energy associated with this action.

-2 applications of your particular type of wave. What are they used for? How are they used/why?

Radio waves are used many for communication in satellites, computers, radio communication, broadcasting, and radars. They are naturally made by lightening or other astronomical objects. Artificially, they are made by burning materials like wood. This website also shows visually how radio waves are made:

Radiolab- Color

I found the radio lab on color both intriguing and very informative. It certainly changed my perspective on how I viewed the sky, and what color means to different cultures in different periods of time. Although I have heard of the bizarreness of Homer not mentioning blue in any of his writings, I had never truly understood the reason. This all became especially clear to me with the example of one of the scientist’s daughter, Alma. This scientist and his wife agreed on never telling their child that the sky was blue. When finally asked, the scientist could see the struggle for the child to determine what color the sky exactly was. Finally, after debating between white and blue,  Alma decided the sky was blue. If Alma, or any of us really, had grown up in Homer’s time where we would not have the experience of seeing blue so often, how would we see the sky? Along with the comment on Homer’s take on colors, I found the idea of tetrachromats very interesting. The fact that there are some people out there who can see more than the “normal” human can, is really incredible. I even looked up online tests to see if I was one, but failed each test. How can this talent can improve your life’s existence? Can it at all? The tetrachromat a scientist found happened to also be an interior designer. Perhaps this skill is especially abundant to those in the arts? This remains unclear, but I found her occupation along with her newfound skill an interesting combination.
