Light & Eyes
Subatomic particles with a positive charge
protons
A group of atoms stuck together
molecule
Someone with the inability to distinguish color is said to be
colorblind
All matter is made up of
atoms
The lowest point of a wavelength
trough
Located outside the nucleus and have a negative charge
electrons
Dalton's First Principle of Atomic Theory
All matter consists of particles called atoms.
The primary colors of light
Red, Green, Blue
Traits that are passed down from generation to generation
hereditary traits
The distance between the crests is called the
wavelength
The center of an atom is called the
nucleus
Dalton's 2nd Principle of Atomic Theory
Atoms of a specific element are identical in mass and properties
True or False: People who are colorblind see no color
False
the simplest component of a substance that cannot be broken down
element
The cells in the retina have special chemicals in them that react to different colors and based on how those chemicals react, they send information down the optic nerve to your brain
Cones
Anything that takes up space and has weight
matter
Dalton's 3rd Principle of Atomic Theory
Atoms of different elements combine in simple whole-number ratios to form chemical compounds.
When light waves overlap, we say that they have _________________ with each other.
interfered
a specialist in the branch of medicine concerned with the study and treatment of disorders and diseases of the eye
ophthalmologist
The cells in the retina that detect the presence or absence of light but give no information about color.
rods
This holds atoms together in a molecule
chemical bonds
Dalton's 4th Principle of Atomic Theory
Chemical reactions involve the separation, combination, or rearrangement of atoms; atoms are not destroyed or created.
If you are seeing the color yellow...which cones are active and which cone is inactive?
Red, Green
Blue
When an object is heated, what happens to the motion of its atoms and molecules?
Move faster and further apart. This is the reason the object expands.
