Blue is a color that lies between violet and green on the spectrum of visible light.
Tell me more about the spectrum of visible light
Well... my understanding is that light is electromagnetic radiation.
ok are there any colors outside the spectrum?
In a manner of speaking. Wavelengths less than 390nm or greater than 700nm wouldn't really have a color.
ok thats alot of techy information for a non techy guy but good to know :)
Heh. Well people just see color in different ways. It's quite personal. But color doesn't mean much if it is outside the visible spectrum.
can we relate the rainbow to a spectrum? since there are so many colors at once being displayed
Yeah. You can think of the rainbow as a part of the spectrum. But imagine millions of 'invisible' colors extending beyond the ROYGBIV you can see.
oh good to know. Is blue your favorite color?
Color psychology
"color psychology"' is the study of hues as a determinant of human behavior. Color influences perceptions that are not obvious, such as the taste of food. Colors can also enhance the effectiveness of placebos. For example, red or orange pills are generally used as stimulants. Color can indeed influence a person; however, it is important to remember that these effects differ between people. Factors such as gender, age, and culture can influence how an individual perceives color. For instance, heterosexual men
The main source of information about celestial bodies and other objects is visible light, or more generally electromagnetic radiation. Observational astronomy may be categorized according to the corresponding region of the electromagnetic spectrum on which the observations are made. Some parts of the spectrum can be observed from the Earth's surface, while other parts are only observable from either high altitudes or outside the Earth's atmosphere. Specific information on these subfields is given below.
Observational astronomy Radio astronomy.
Radio astronomy uses radiation with wavelengths greater than approximately one millimeter,
