what is it lights? where does it come from ?what does light have to do with color ?
lights what is it? where does it come from ?what does light have to do with color ?
life is a kind of energy that travels in waves it is made when matter is heated up or gains energy excess energy is released in part as light energy is called electromagnetic radiation.
when we talk about light we usually mean visible light which is the light that we can see with our eyes but there are more types of electromagnetic radiation that are invisible to us putting radio waves microwaves X-rays and gamma-rays.
scientists can detect and measure invisible radiation with special tools because there was visible light all these types of radiation are called the electromagnetic spectrum all electromagnetic radiation travels in waves but different types have different wavelength the wavelength of electromagnetic radiation or light is connected to how much energy it has light with a longer wavelength like a radio wave has less energy while light with a shorter wavelength like galleries has more energy visible light makes up only a tiny part of the electromagnetic spectrum.
But it includes every color we can see the most important source of light here on Earth is the Sun we call ordinary sunlight white light but it actually include all the colors of visible light colors can be revealed when white light goes through a prism
when light passes through a prism or something like it it slows down a little bit some parts of the lights and the light spreads out usually when we talk about a rainbow we say it is made of seven colors red,orange,yellow,green,blue,indigo,
violate
each color has a different wavelength
RED has the longest wavelength in the spectrum of visible light
VIOLATE has the shortest wavelength all the other colors have wavelengths in between the two the colors of a rainbow are always in the same order because the colors are arranged according to their wavelength red is always on the outside because red has the longest wavelength and violet is always on the inside because Violet has the shortest wavelength electromagnetic radiation with a wavelength outside
The visible light spectrum is invisible to our eyes light with a longer wavelength has reddish red our eyes can see infrared light light with a shorter wavelength than violet Violet we can see is called ultraviolet look at an object we are actually seeing the light that is bouncing off it green leaf looks green because the leaf absorbs all of the colors of the spectrum except for green it looks
which it reflects when the green light enters our eyes our brain tells us it looks green things that looks white are reflecting almost all of the visible light shining on them at things that look black are absorbing almost all of the visible light shining on them light visible and invisible is all around us it travels from its source as a waived bringing energy with it without light there would be no colors take a look at the world around you and remember everything you can see is just different wavelength of reflecting light
