What are primary colors
3162016 copycgrahamphysicscom 2016
Not in Physics ndash we are talking about light
3162016 copycgrahamphysicscom 2016
Red Orange Yellow Green Blue Violet
Mixing all these colors together we get what color
3162016 copycgrahamphysicscom 2016
Primary colors in Physics are

You are about to see an artists impression of a famous moment in sciencehellip
You will have 20 seconds to look at the picture
Try and observe and memorize as many details as you can
End 3162016 copycgrahamphysicscom 2016
In the picturehellip
1 Is the scientist wearing a jacket or just a waist coat
2 Does the scientist have short hair or long hair
3 The scientist was holding something What was he holding and in what hand
4 Which famous scientist is this and what was he doing
Jacket and Waist coat
Long hair
Prism in right hand
Newton discovered the dispersion Of light
3162016 copycgrahamphysicscom 2016
Would this have been easier
3162016 copycgrahamphysicscom 2016
How would our world change
Discuss what would happen to the way we live if we couldnt see in color
What things would be affected
Would it a positive change

On the back of the retina are rods and cones
3162016 copycgrahamphysicscom 2016
Cones Responsible for color vision
Pigments of cones are of three types blue green and red 3162016 copycgrahamphysicscom 2016
After image
To see an after-image one need only look intently at any object for a short time then direct the eyes at a blank surface like a wall
Every color has an opposite and although individuals perceptions do vary the range of after images seen is consistent
Look at the center dot for 20 seconds

How does it work
Cyan is made up of and light When you
stare at the part of the image the blue and green light
sensitive cells become desensitized After this when you look at the
white screen the all the colours fall on your retina however only the
cells are stimulated because the and cells
are still inactive Your brain only sees where the was
Now explain why yellow forms a blue after Imagehellip

Yellow rods are desensitized which means green and red rod are not stimulated as yellow is a mix of red and green Only blue rods are stimulated 3162016 copycgrahamphysicscom 2016

After image
To see an after-image one need only look intently at any object for a short time then direct the eyes at a blank surface like a wall
Every color has an opposite and although individuals perceptions do vary the range of after images seen is consistent

Cyan is made up of and light When you
stare at the part of the image the blue and green light
sensitive cells become desensitized After this when you look at the

are still inactive Your brain only sees where the was

How does it work
Cyan is made up of and light When you
stare at the part of the image the blue and green light
sensitive cells become desensitized After this when you look at the
white screen the all the colours fall on your retina however only the
cells are stimulated because the and cells
are still inactive Your brain only sees where the was
