Where does the name redshift come from?
The term "redshift" comes from the shifting of light towards longer (redder) wavelengths as an object moves away from an observer, as described by the Doppler effect in physics. In astronomy, redshift is used to measure the speed and distance of galaxies moving away from us in the expanding universe.
How do the colors of incandescence change with temperature?
The colors of incandescence change from red to orange to white as the temperature increases. This is because higher temperatures cause objects to emit shorter wavelengths of light, shifting the color from the lower end of the visible spectrum (red) to the higher end (white).
Where do visible light waves come from?
Visible light waves are produced by the motion of electrically charged particles (such as electrons) within atoms or molecules. When these particles move and change energy levels, they release photons of light in the visible spectrum. Sources of visible light waves include the sun, light bulbs, and other sources of electromagnetic radiation.
What object can absorb and emit a continuous spectrum?
Anything white. At least within the visible spectrum. The incident light is absorbed and re-emitted with little or no change. This is why a white wall appears red in a red light, yellow in a yellow light, etc. In contrast, a colored wall, say red, will actually appear black in blue light since all of the incident light is absorbed.
Does the suns spectrum change throughout the day?
No, the sun's spectrum remains relatively constant throughout the day. The changes we see in sunlight, like color shifts during sunrise and sunset, are due to the scattering of light in the Earth's atmosphere, not changes in the sun's spectrum itself.
Is there a color or colors that no one ever seen and why is that?
Yes , there may be , because human visible range is between 400nm to 700nm wave length of spectrum,if we change our visible range then we can observe several new colors, but question is how.
The colours do not change their position in the spectrum explain?
The colors of the visible spectrum are arranged in a specific order based on their wavelengths, from longest to shortest: red, orange, yellow, green, blue, indigo, and violet. This order does not change because it is determined by the physics of light and the way our eyes perceive different wavelengths. The specific position of each color in the spectrum is consistent and helps us understand the properties of light.
How does wavelength change as you move from left to right on the spectrum?
As you move from left to right on the electromagnetic spectrum, the wavelength decreases. This means that the wavelengths get shorter as you go from radio waves to microwaves, then to infrared, visible light, ultraviolet, X-rays, and finally gamma rays, in that order.

A frequency of 1GHz on a spectrum analyser corresponds to what frequency in the Ku band?
The Ku band of microwave frequencies ranges from 12 to 18 GHz. A frequency of 1GHz is not in the Ku band. There is no correspondence. Is the 1GHz setting on the spectrum analyzer a center frequency? Or is it one of the ends of the spectrum analyzed? Is it the width of the spectrum being analyzed? And if it is the latter, what is its center? Knowing these things will still not change the answer given, but may help to "sort out" a possible problem with the question the way it is written.
Why does the color of things change when they are hot?
as a surface heats up the wave lengths of energy emitted by the surface shorten. If the surface gets hot enough the wave lengths generated will reach the visible spectrum starting at the longer wave lengths eg red and as the surface gets even hotter the wave lengths shorten even more heading towards the white and blue end of the visible spectrum.
What causes the color change in the Ferric chloride and phenol reaction?
The color change in the reaction between ferric chloride and phenol occurs due to the formation of a complex between the two compounds. This complex has a different absorption spectrum compared to the individual compounds, resulting in a visible color change.
What is the political spectrum based on?
change
How does radiation change across the electromagnetic spectrum?
Radiation changes across the electromagnetic spectrum based on the wavelength and frequency of the electromagnetic waves. As you move from radio waves to gamma rays, the wavelength decreases and the frequency increases. This results in higher energy levels and greater potential for ionization as you move towards the gamma ray end of the spectrum.
What is the smallest portion of the EM spectrum?
The EM spectrum is a continuous uniform range/domain that has no inherent internal or external boundaries. All delimitation are artificial constructs imposed upon it by man. If you wish to talk about any EM range you agree to definite it for discussion. It does not exists as a natural phenomena.
How can you use the em spectrum to explore the universe?
The HST uses EM waves to find things through echolocation or firing a beam of EM waves (or sound) at objects and seeing what a planet or star has done to change the light. Ultrasound works this way.
What will happen to an objects spectrum as the object moves away from you?
the spectrum change with direction, either from you or away
