rainbows are light separated into it's 7 colours. You can only see a rainbow from one direction and the rainbow is created when the light reflects off the water thus separating it into the seven colours. You can also see rainbows sometimes when watering a garden or really anytime when there is water in the air.
this is called refraction. light is made up of seven different colours as seen in a rainbow. a glass prism breaks the light up into its base colours. this is the same principle a rainbow is made by only rainbow uses watere droplets to refract the light.
We see colours because of the light absorbed by the object in view. White paper absorbs all the colours of the rainbow - so only white is reflected. A red stop sigh absorbs all colours except for red & white.
Beacause of the light reflecting of the detergent
Because "color" is an interaction between the visible light portion of the electromagnetic spectrum and the light sensitive parts of our eyes. Our eyes have evolved 4 different receptors--one each for Red, Green and Blue and another for violet. A rainbow actually contains millions of colors, but we have evolved to categorize most of the wavelengths in the visible spectrum as one of the primary colors and their combinations.
The sunlight hits the glass of water and then the light disperses out as a spectrum of colour (rainbow). This is because sunlight is white light and white light contains the 7 colours of the rainbow. When it hits the glass the colours refract and disperse out as the spectrum of colours, which we see as a rainbow.
The Rainbow as you see it are the colours which constitutes the light you see or rather percieve.
you get the colours in a rainbow because of the sun magnifying through the rain and projecting the coulours of the rainbow. if you squint at a light you will see a rainbow around it. it works a bit like that
Because the sunlight which is white gets disperced (split) into the colours of the rainbow hence the name rainbow.
This Q&A is about light colours. Paint colours are substances, and different from light colours.If you hold up a glass prism to a beam of sunlight, you'll see the light form a rainbow of colours. This is called the spectrum. It consists of all the colours that make up "white" light.Although you might be able to see seven colours in the spectrum, the white light is really made up of three basic colours. These are called the primary colours because they cannot be made from any other colours. The primary colours of light are red-orange, green, and violet blue. The other colours you see in spectrums or rainbows are made by a mixture of the primary colours.When the naked eye looks at the spectrum, it can see three mixed colours, which are called secondary colours. The secondary colours in light are green-blue, yellow, and magenta-red. You can produce these colours by mixing the primary colours in certain combinations.
The same as in a rainbow - red, orange, yellow, green, blue, indigo, violet.
When sunlight passes through raindrops, the rain drops act like a glass prism. The sunlight is split into the rainbow colours in the sky, and a rainbow appears.
