Posted by Anonymous on Friday, April 18, 2008 at 1:55pm.

1)Put the types of radiation of the electromagnetic spectrum in order from:

a)longest to shortest wavelength
b)greatest to lowest energy
c)slowest to fastest speed

A)radio,microwave,infrared,light,x-rays,gamma rays

B)gamma-rays,infrared,light,microwave,radio

I couldnt find C. I got this from wiki,my book and another site

2)Put the following colors in order of smallest to largest frequency: blue,orange,green. Explain that logic for your order.

blue,green,orange don't understand this from a site:

"When a beam of white light (sunlight) is passed through a PRISM, as shown in figure 1-18, it is refracted and dispersed (the phenomenon is known as DISPERSION) into its component wavelengths. Each of these wavelengths causes a different reaction of the eye, which sees the various colors that compose the visible spectrum. The visible spectrum is recorded as a mixture of red, orange, yellow, green, blue, indigo, and violet. White light results when the PRIMARIES (red, green, and blue) are mixed"
