A red shift in the spectrum of the light from an object indicates the object is moving where?
A red shift in the spectrum of light from an object indicates that the object is moving away from the observer. This is a result of the Doppler effect, where the wavelengths of light are stretched as the object moves away, causing a shift towards the red end of the spectrum.
Why do some stars appear red?
generally speaking things appears the colors that they do because of two things, the way our eyes and brain perceive them and the way the object absorbs and reflects different wavelengths of the light spectrum. our minds interpret the light spectrum as the colors red, orange, yellow, green, blue indigo and violet and any combination of these colors. when light strikes an object, the object absorbs and reflects light waves, for instance if an object appears red to you, it's because the surface of the object absorbs all the other light wavelengths except red, which bounces back to our eye and causes the object to appear red. strangely enough, when all colors of the light spectrum are bounced back to us, we perceive the object to be white and when none of the colors are reflected, we perceive the object to be black!
What color of the rainbow reflects the most light?
A rainbow is composed of light. Light does not reflect light.
A red shift in the spectrum of the light from an object indicates the object is?
moving away from us.
What does a red shift in the spectrum of light from an object indicate about the object?
Usually, that the object is moving away from us. It may also mean that the light comes from a "gravitational well", that is, that the light has to escape from gravity before it reaches us - this will make the light lose some energy, and shift towards the red part of the spectrum.
What color does not reflect any light?
Black. it absorbs the entire visible spectrum, whereas white reflects the entire visible spectrum.
What color will reflect all colors?
The color that we see is not the color of the object in question, but the color of the light it reflects. This means that a "green object" absorbs all colors of the visible spectrum except for green light, which it reflects back to our eyes. White light is the combination of the entire visible spectrum combined. Thus a "white object" reflects all colors of light. On the opposite side of this question, a "black object" absorbs all colors of light, because "black" is the absence of color.
Why in Light refraction do black objects remain black?
Light "refraction" is the bending of light as it passes through a transmitting medium, Refraction has nothing to do with black objects. A black object reflects no parts of the visible part of the spectrum, it absorbs them all. A white object reflects all parts of the visible spectrum. A red object reflects the red part of the spectrum, absorbing the rest.
Why do object appear white?
A white object emits light in all/most of the visible spectrum evenly.Because it reflects all the light back.
If an object reflects all the light falling upon it the object would be?
If an object reflects all the light falling upon it, it would appear white to our eyes. This is because white is a combination of all colors in the visible light spectrum.
What color does a purple object reflect?
A purple object reflects primarily purple light, which is a combination of red and blue wavelengths. When light shines on the object, it absorbs all other colors of the spectrum and reflects back only the purple light to our eyes.
What colour will an object appear to be under white light if it reflects all the colours of light?
The object will appear white. When an object reflects all colors of light equally, it will appear white because white light is a combination of all colors in the visible spectrum.
What colour will an object appear to be under White light if it reflects all the colours of life?
The object will appear white under white light if it reflects all the colors of light. This is because white light is a combination of all visible colors in the spectrum.
What does an object do to light so you can see it?
Reflects all light beams which have the wave length of the color of that object. Each color has a particular wave length in the electromagnetic spectrum.
What happens when a light hit a black object?
An object appears black because it absorbs all the colors of the visible spectrum. If we idealize the object to make it perfectly absorptive, it absorbs all of the white light that strikes it and reflects none. In the real world, some light is always reflected. If the object appears black or dark gray, then it reflects small amounts of all colors of the spectrum.
When a object reflects all light wave what color does it appear to be?
If an object reflects all light waves, it appears white to the human eye. This is because white light contains all the colors of the visible spectrum, and when they are all reflected off an object, our eyes perceive it as white.
When an object reflects all wavelengths of visible light what color do you see?
When an object reflects all wavelengths of visible light, you see it as white. This is because white light is composed of all the colors of the visible spectrum, and an object that reflects all these wavelengths appears white to the human eye. Conversely, if an object absorbs all wavelengths, it would appear black.
