... [Show More] is called the __________
__________ __________
wavelengths - ANS-different colors represent different __________
pigment - ANS-molecule that absorbs light energy
transmitted - ANS-All light energy that isn't absorbed is ____________.
transmitted - ANS-(Transmitted/absorbed?) wavelengths make it to our eyes
absorb; transmitted - ANS-Ex:
Red shirt pigments (absorb/transmit?) all wavelengths of light except for red, which
means red is (absorbed/transmitted?)
white - ANS-color that transmits all wavelengths of light and absorbs nothing
black - ANS-color that absorbs all wavelengths of light and transmits nothing
reflection - ANS-the bouncing back of light from a surface
Refraction - ANS-bending of light waves
median; distortion - ANS-Refraction:
When light changes from one ____________ to another
Waves of light get bent and this leads to _________ in images.
Refraction - ANS-Example of??
Looking at a spoon in a cup of water and it looks bent
Air → cornea → aqueous humor → lens → vitreous humor (bends each time) - ANSRefraction/bending of light:
Air → _________ → _________ humor → _________ → _________ humor (bends
each time)
Retina - ANS-All light beams are converged on a certain point of the _________
emmetropic eye - ANS-normal vision eye
focal point of the retina - ANS-emmetropic eye:
Light converged right on the __________ point of the __________
near
front
concave - ANS-myopic eye
(Near/Far) sighted?
Focal point is in _________ of the retina
Corrective lens is (concave/convex)
