LASER
The difference is in the size of the wavelength blue is smaller than red.
A shadow is where light is not intense.
Any object that has light shone on it would appear in a particular color because the said object absorbs all the other colors of the spectrum and reflects one single color. when the light itself consists of a single color, the color of the object gets modified because the reflected light contains the color of the light and then part that is reflected. For ex, the wall in the question would appear red if the light is only one wavelength but would appear as a combination of red and its own natural color if the light is a combination of different wavelengths.
white light is not a single color..it is made up of 7 different colors which include red and blue and yes it is there in the electromagnetic spectrum between ultraviolet and infrared radiation
A black object absorbs light- black is actually an ABSENCE of light. White, on the other hand, REFLECTS all colors- which, when blended, produces white.
Electric arc welding produces intense ultraviolet light, which is very hazardous to eyes and skin.
The difference is in the size of the wavelength blue is smaller than red.
It produces a secondary color of light.
black
Different frequincies of light cause color, but a photon can not have color because it is only a single particle of light
"Color" is the sensation that a light produces in your eye and your brain. Ultraviolet light is not detected by your eye, so there's no such thing as its color.
Tomato red is extremely intense, so you need a bland, light wall or carpet color, like light beige, light sage.
A shadow is where light is not intense.
I am almost positive it is green
how intense is the light on callisto
Frequency, color, energy in each photon.
It can be any color on the spectrum, as long as it is a pure single wavelength (mono = one) color.
