Light energy is a form of electromagnetic radiation and is found in a segment of the (EM) electromagnetic spectrum.
red= lowest frequency
blue and violet= highes frequency
The EM spectrum encompasses the entire range of ionizing and non-ionizing radiation extending in frequency from approximately 1023 hertz to 0 hertz, or in corresponding wavelengths, from 10-13 centimeter to infinity.

This spectrum includes all forms of classical non-ionizing radiation we are familiar with including ultraviolet light, VISIBLE LIGHT, infrared (light) radiation, microwaves, and radio waves. The spectrum also includes ionizing radiation such as cosmic-ray photons, gamma rays, x-rays.

At eithe end of the visible light spectrum is infared and ultraviolet light and humans cannot perceive these spectrums of light. Red colored light is longer wavelength of light and visible violet light is shorter wavelength.

For a cool chart and more in depth descriptin of the EM spectrum check out the Goddard Space Center's special page on this topic.

A researcher wanted to examine if there is a relationship between color preference (i.e., favorite color: red, yellow, green or blue) and personality type (i.e., extrovert or introvert). He selected a sample of n = 200 participants; each participant took a personality test and identified the favorite color. The collected data are shown in the table below. Do the data indicate a significant relationship between personality type and color preference? Test with p < .01. RED YELLOW GREEN BLUE INTROVERT...

A psychologist is interested in the relationship between color of food and appetite. To explore this relationship, the researcher bakes small coockies with icing of one of three different colors (green, red or blue). The researcher offers cookies to subjects while they are performing a boring task. Each subject is run individually under the same conditions, except for the color of the icing on the cookies that are available. Six subjects are randomly assigned to each color. The number of...
