The color red is the wavelength of the electromagnetic spectrum that is about 650 nanometers (within the range of what is commonly called "visible light"). This represents a particular wavelength (inversely, a particular frequency) that photons of light exist at.
When a photon of this kind exists, it is generally because an atom of a substance has emitted a photon of this wavelength/frequency (a "red" photon). This can happen when a substance receives broad-spectrum (white) light, and absorbs all but the red part of the visible spectrum.
After the red photon has been emitted, it is absorbed by a molecular/enzyme complex called "rhodopsin" in the retina of the eye, where it, then, produces a particular energy "signal" for the optic nerve. This signal travels back to the visual cortex in the occipital lobe of the brain (in the back), and it is "decoded" as "red".
What else can I help you with?
What happens to a red object when light is shone on to it?
When red light shines on a red object, the object will reflect the red light and appear red. If white light shines on a red object, the object will absorb all colors except red, which it will reflect, making it appear red as well.
If an object absorbs all wavelengths of light except red what color will it appear?
The object will be red, due to the red light of the spectrum being reflected.
What would a white object appear under a red light?
A white object would appear to be red under a red light because the object reflects red light and absorbs other colors. This is because the color of an object depends on the wavelengths of light it reflects.
For an object to appear red what must the object do to red light waves?
For an object to appear red, it must absorb all other colors of light and reflect red light waves. The object's surface reflects only the red light waves, while absorbing all other colors. This selective reflection is what gives the object its red appearance.
What colour would a red object look under a red light?
The red object would appear red under a red light because objects primarily reflect the color of light that is shining on them. Since red light contains mainly red wavelengths, the object would still reflect red light and appear red.

Does looking through red glass at a red object with a white background look white?
No, looking through red glass at a red object with a white background will not make the red object appear white. Instead, the red object will appear darker or more saturated against the white background. This is because the red glass will filter out most of the red light, making the object's color more pronounced.
What colour will a yellow object appear if only Red light is shone on it?
The yellow object will appear dark because it reflects yellow light, which is a combination of red and green light. Since only red light is being shone on it, the object will not reflect any light and will appear black.
Red object when seen to a thick blue glass appear?
Red+Blue=Purple
What color would a red object appear to be if you shone a green light on it?
it would appear black.
What color is a white object when red and cyan light shine on it?
The white object will appear red because all colors of light are absorbed by the object except for red and cyan. The red light is reflected to our eyes, resulting in the object appearing red.
If an object reflects red and green light what color does the object appear to be?
An object that reflects green and red light would be some shade of yellow or orange, depending on the proportions.
What is true about an object that looks red?
An object that looks red is absorbing all colors of light except for red, which is being reflected off the object and detected by our eyes. This object appears red because our eyes perceive the red light that is bouncing off of it. The color red has a longer wavelength compared to other colors, making it appear red to our eyes.
