The perception of COLOUR The colour is the feeling you get from the sense of sight from the incident light refracted or reflected by the surfaces of objects
Can you see it ??? incident RED reflected
When white light hits an object, some colours are reflected and some are absorbed. Reflected colours travel to your eye and give the object its colour. give the object its colour. Once more,
When you see an object, the feeling of white appears as it reflects all the incident light. The sensation of black appears when all the incident light is absorbed.
yellow Any other colour such as yellow appears when the incident light is only reflected in the part of this colour and the rest is absorbed.
In 1666, Isaac Newton proved the relationship between light and colour by passing a ray of white light through a triangular prism.
The light was decomposed into a variety of colours from red to violet. They are the colours of the rainbow
Different colours of light each have a different wavelength. Violet light has the shortest wavelength and is refracted most. Red light has the longest wavelength and is refracted least.
Now, you see !!!
The RAINBOW is a phenomenon of colour. When sunlight passes through raindrops, white light decomposes into seven colours, as in Newton’s prism.
The RAINBOW is an optical and meteorological phenomenon that causes the appearance of a continuous spectrum of light in the sky when the sun's rays pass through raindrops
The seven colours of the rainbow are Red, Orange, Yellow, Green, Cyan, Blue and violet.
How can you remember the colours of the rainbow and their order ?
Light. Colour How do we see colours? White light, the light you see from globes, fluorescent tubes or the sun, is made up of lots of different colours.
This student is looking at many colors on his computer screen
Color White light is not a single color; it is made up of a mixture of the seven colors of the rainbow. We can demonstrate this by splitting white light.
Spectrum D. Crowley, Spectrum To know how a spectrum (rainbow of colours) is made.
SUBTRACTIVE COLOUR MIXING SUBTRACTIVE COLOUR MIXING ADDITIVE COLOUR MIXING ADDITIVE COLOUR MIXING.
How do we see colour?. Electromagnetic Energy being transferred by the Sun.
Light and Color Standard: S8P4c. Explain how the human eye sees objects and colors in terms of wavelengths. EQ: How do humans like yourself see color?
KeiErica Perry & LeAmbreya Long. The colors around you are due to the way the objects reflect light Different materials have different natural frequencies.
All About Light. Why does the straw look bigger in the water? Because water magnifies the size of an image. Because light travels slower through the water.
PROPERTIES OF VISIBLE LIGHT
(c) McGraw Hill Ryerson Properties of Visible Light The wave model of light describes light as a wave that travels through empty space. Light.
The Electromagnetic Spectrum
Prisms, total internal reflection, polarization, how we see color, how vision is corrected and rainbows. Light and Color.
