Glow in the dark objects need exposure to visible light, preferably natural sunlight or artificial light, to extract energy. Once exposed, the object will store this energy and release it as visible light in the dark. UV light can also be used to quickly charge the object.
A yellow object under a yellow light will appear very bright and vibrant, as the object will reflect the light in a consistent color. This can potentially make it difficult to differentiate between the object and the surrounding light source.
No, under green light a red object will still appear red. This is because the color of an object is determined by the wavelengths of light it reflects, and green light does not change the wavelengths that a red object reflects.
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.
Why do you call it a "white object" ? Could it be because it looks white under white light ... light composed of every color ? Well then, the object must reflect every color. So it appears to be the color of whatever light you illuminate it with. Yellow under yellow light, etc.
A cyan object will appear black under red light because red light is absorbed by cyan objects. Cyan is a combination of green and blue light, so when only red light is present, there is no light for the cyan object to reflect or absorb.
The shadow of an object under a street light will point away from the light source, opposite to where the light is coming from. This is because the light source casts the object's shadow in the direction opposite to its position.
A yellow object under a yellow light will appear very bright and vibrant, as the object will reflect the light in a consistent color. This can potentially make it difficult to differentiate between the object and the surrounding light source.

A cyan object will appear black under red light because red light is absorbed by cyan objects. Cyan is a combination of green and blue light, so when only red light is present, there is no light for the cyan object to reflect or absorb.
The object absorbs all colors of light except for red, which is reflected off the object and is what we perceive as the color red.
If an object absorbs all colors of light and reflects none, it will appear black under white light. This is because black is the absence of any reflected light.
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.
it does because the heat on the light causes the object under it warm
Sure!
It would be black becasue the object would absorb all the red light, and there would be no green light for it to reflect
