Light
the ability of light waves to be taken into an object or medium
What is absorption
process whereby light bounces back from an object at the same angle and intensity that the object received it
What is reflection
the small section of the electromagnetic spectrum that human eyes can detect
What is visible light
is the most important source of light on earth.
What is the sun?
a molecule in plants that absorbs certain wavelengths of light
What is chlorophyll
the change in direction of light when it goes from one medium into a different medium
What is refraction
a molecule in plants that absorbs certain wavelengths of light
what is chlorophyll
visible light that contains all of the colors of the visible spectrum
What is white light
special light-sensitive cells in the retina that allow us to see colors and fine details
what are cones
the ability of light waves to be taken into an object or medium
what is absorption
cells on the retina that detect different wavelengths of light and send these signals to the brain
what are photoreceptors
a measure of how many wavelengths pass a given point per second
What is frequency
cells in the retina that are sensitive to all light but do not distinguish color
What is rods
the total length of one complete wave, the distance from one point on a wave to the next similar point
What is wavelength
cells on the retina that detect different wavelengths of light and send these signals to the brain
What are photoreceptors
the passing of light through an object or medium
What is transmission
the layer of cells at the back of the eye where light-sensitive cells are found
what is retina
