Colours are just light waves of different frequencies and wavelengths.
Colour -Wavelength
Red Light is ~700 Nano Metres Orange Light is ~ 600 Nano MetresYellow Light is ~ 570 Nano MetresGreen Light is ~ 520 Nano MetresBlue Light is ~ 490 Nano MetresViolet Light is ~ 420 Nano Metres
Frequency = speed / wavelength. On the other hand, light of different frequencies looks to our eyes as different colors. Some frequencies - most, in fact - can't be seen at all.
The cloth would be wite because if it were any other color the colored light would mix with the color of the cloth and make a different color.
Particle theory of light can explain Photoelectric Effect,Compton effect,Pair production.... wave theory of light can explain interference,refraction...
It would be come a white light( it will show up to have a rainbow streak on the screen though)
No, the wavelength determines the color of the light. 700nm corresponds to red, 400nm to about purple, and in between are the rest of the visible colours.
Because it is.
light can be energy and light can be consider as matter too.
Violet light has shorter wavelength than any other color. I looked it up.

ultraviolet light
The difference in energy between the energy levels determines color of light emitted when an electron moves from one energy level to another.
Basically channels are the basic elements of color information and the Levels are the light information of an image. We can control the color by giving light prominence to a particular channel using levels. Levels will only identify the dark, mid-tone, highlight value of an image. Levels also able to modify light values on a channel.
