The visible portion of the Electromagnetic Spectrum. Visibility to the human eye is determined by the Frequency (or wavelength) of the light.
Mixing green and blue light produces cyan. That's a kind of light blue.
A "white surface" is one that reflects all colors of light. That's why it looks white when a white light shines on it, and that's why you call it "white". If only red light shines on it, then it looks red.
This happens because inside the prism it reflects the light many, many times and at some stage as it is being reflected the light fractures and breaks up into the colours that you see when you look through it.answer 2 Well, not quite. In a transparent solid, such as glass or clear plastic, all of the wavelengths of light do not travel at the same speed!Whereas in air, essentially all wavelengths travel at the same speed.So when light makes the transition from air to the clear prism, some of the colours travel slower; and this we see as, and call refraction.The differing velocities, of various light colours through glass, are a serious problem in the design of photographic lenses, microscopes etc. It is known as chromatic aberration.
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.
It absorbs all colors in the white light, except for the blue, which it reflects and scatters, and it winds up appearing blue to our eyes. That's a big part of the reason why we call it "a blue box".
the name given to two colours that produce white light are called complementary colours.
White light can be split up into lots of different coloured light waves using a prism. We call this range of colours the visible spectrum.

By Dispersion Of light (We call the phenomenon of spiliting of white light into 7 colours as dispersion of light.).......... You Can use Prism.....

When equal amounts of Red Green and Blue light are combined, they produce white light. By adding the colours together to produce white, we call these additive colours. It basically means it changes colour
Mixing green and blue light produces cyan. That's a kind of light blue.
White light is a mixture of light of different colors. Some mixing proportions trigger a response in our visual system that we call "white".

Is spectrum too simplistic an answer?
