As you move from the blue region of the electromagnetic spectrum to the red region of the electromagnetic spectrum, what happens to the frequency of the light?

Perhaps if you were to plug the appropriate variables into the frequency and wavelength calculator found here you might find the answetr: http://www.1728.com/freqwave.htm Sep 12 08, 12:04 PM

The blue (or violet) end of the visible spectrum is the highest frequency of visible light, and the red end is the lowest frequency. The wavelength of violet light is around 400nm (with a frequency of around 7.5 x 10^14 Hz), and that of red light is around 700 nm (with a frequency of around 4 x 10^14 Hz). Visible light is only a very small part of the electromagnetic spectrum! http://en.wikipedia.org/wiki/Electromagnetic_spectrum Sep 12 08, 8:24 PM

The frequency will drop as you venture from blue/purple to red. If you take a look at the spectrum as a whole, visible light is but a small protion. Red is one of the lower frequencies, hence infrared light. Infrared is lower than that of the visible color red and is regarded as heat. To the right of the color blue/purple (if we line it all up) is Ultraviolet, widely known to come from the sun. To directly answer the question, the frequency drops, however knowing those two extra waves helps with remembering. (It helps me!) Here are some corrections: when I said to line them up, I meant to order the waves from low to high frequency. And I also meant to say infrared is a lower frequency than normal red. Sorry for the strange wordings! And here is my source: www.lbl.gov/MicroWorlds/ALSTool/EMSpec/EMSpec2.html Sep 13 08, 5:12 PM
