What color of light is lowest on the spectrum?
Red is the lowest on the spectrium. Then it goes orange, yellow, green, blue, and violet is the hightest.
What is the relationship between color and light?
Relationship between color and light Different wavelengths, and thus different frequencies, of light are perceived by the human eye as colors. The visible light spectrum ranges from 400nm to 700nm, with 400nm being perceived as violet and 700nm being perceived as red light. The energy of the light dictates its color. An easy way to remember the order of the colors of the visible light spectrum is "ROY G. BIV", or Red Orange Yellow Green Blue Indigo Violet. When one sees an object as a certain color (green leaves on a tree, perhaps), this is due to the light wavelengths that are and are not being absorbed. In the case of green leaves, the chloroplasts absorb most of the wavelengths of the visible spectrum except green. Thus, green light is reflected off of the leaf and the rods in ones eyes perceive the wavelength as green. White Light and Bright Colors Generally speaking, whiter light (comprised of equal amounts of all colors) makes colors appear more natural and vibrant. However, some portions of the spectrum are more important to a light's color makeup than others. Red, blue and green-the primary colors of light-can be combined to create almost any other color. This suggests that a light source containing balanced quantities of red, blue and green light can provide excellent color appearance even if this light source is deficient in other colors in the spectrum.
What are some of the star characteristics that can be identified by spectral analysis?
Spectroscopic surveys are based on the fact that the colors you see in everything are not in the object being observed, but is the result of the fact that the elements that make up the object, are reflecting that part of the spectrum of light that strikes it. Spectroscopic analysis will give researchers an idea of the basic makeup of the star.
How are red-shifted and blue-shifted waves different?
The "doppler effect" (see link below) describes what happens to an observer who is moving toward or away for the source of any type of propagation wave such as light or sound.If we are moving rapidly toward any object which is transmitting an electromagnetic wave - or if it is moving toward us - the waves are "compressed" and we perceive them to be of a higher frequency than was originally emitted. With light, "higher frequency" means "more bluish", while "lower frequency" means "more reddish".So scientists refer to the increasing wave frequency as a "blue shift", while a decreasing frequency, meaning movement away from us, is a "red shift".
Is indium name after India?
No, it is named from the blue (indigo) lines in its spectrum.
If an object is blue what color of light is being absorbed by the object?
The object appears blue because it is absorbing colors in the red and yellow range of the spectrum and reflecting blue light.
What colors do blue absorb?
Blue objects absorb all colors of light except for blue. When light hits a blue object, the object absorbs the other colors within the visible spectrum, reflecting or transmitting the blue light.
What color is Neptune and why is it that color?
Neptune appears blue due to the methane gasses in the atmosphere absorbing the red light spectrum and reflecting the blue light spectrum back into space.
When light waves strike a blue object what happens to the light waves of all colors?
When light waves strike a blue object, the object absorbs most of the colors in the light spectrum except for blue. Blue light waves are reflected off the object, giving it its blue color.
When an object appears to be yellow what color of the spectrum is reflected?
Yellow light is made of primary colors red and green. Yellow objects absorb the blue light and reflect the red and green, so we see yellow. If I'm wearing a green shirt, the color reflected is Green. All others are obsorbed. Ta-da!
Why does an object appear blue in white light?
An object appears blue in white light because it absorbs all of the colors in the visible spectrum except blue, which it reflects. The reflected blue light is then what we perceive with our eyes as the color of the object.
Would a blue object stay blue if you put it under a red light?
The physical property of something being blue is purely a result of the wavelength(s) of light it reflects. Blue objects are blue because they reflect only light that lies within the blue spectrum (450 nm - 475 nm). If you put a blue object under a red light, the object will still maintain it's properties of reflecting blue light. Thus, the object doesn't change, however because no blue light is present, the object will not appear blue when viewed under the red light. Rather it will take on a darker shade, probably a black color.
How is red and blue shift related to the electromagnetic spectrum?
The EM spectrum includes visible light. If an object moving very fast comes toward a reference point, the visible light radiating off it/reflecting off it gets "squashed": the wavelengths become shorter. This makes the visible light accquire a blue tinge. The opposite happens for an object heading away, and it looks more red.
What light waves does a blue object reflect?
The wavelengths are corresponded to the color of the light. A blue object will reflect any light radiation expect the color blue. It will absorb the blue light.
Why does a blue object appear black when illuminated with light?
A blue object appears black when illuminated with light because it absorbs most of the light that hits it, including the blue light that gives it its color. This absorption of light prevents the object from reflecting enough light to appear blue, making it appear black instead.
What colour would a red shirt appear when exposed to white light?
A white shirt is, basically, reflecting all colours of the electromagnetic spectrum which it is exposed to. So for white light it is reflecting red, orange, yellow, green, blue, indigo, violet. If you only expose it to red light (with a wavelength of ~650nm), it will reflect only that light. Therefore, the white shirt will appear red.
What colors of white light does a blue object absorb?
A blue object absorbs white light that contains all colors except blue. When white light shines on a blue object, the object appears blue because it reflects blue light and absorbs all other colors in the white light spectrum.
