firefly
absorbed
When light is absorbed it, doesn’t pass through the object
transmitted
When light is transmitted it goes through the object
reflected
light bounces off the object
transparent object
a window, this is where light passes through
translucent object
tissue paper, where light sort of passes through
opaque object
a desk because light is absorbed and doesn’t pass through
law of reflection
The angle of incidence is equal to the angle of reflection
Concave Mirror
Images appear larger used for upside down view
Convex Mirror
Images appear smaller and used for bigger view
real vs. virtual image
Real image is where light converges and virtual is where light diverges
why refraction occurs when light moves from air to water
because air is a less dense medium, so when it goes to a denser substance, it bends because it moves slower when going in
Optic nerve
electric signals from eye to brain
Retina
tissue where image is formed
Sclera
white part of eye that maintains eye shape
Ciliary muscle
focusing the eye
Lens
changes direction of light
Iris
the colored part that controls amount of light going in the eye
Pupil
opening where light enters
cornea
it helps focus light
cones
see color
rods
outlines/shapes
aqueous humor
Provides nutrition to eye
virtuous humor
Helps maintain the shape of the eye
the film
retina because image focuses in the eye
the diaphragm
iris because it controls the pupil and how much light enters
the aperture
the pupil because it can adjust itself
the lens
the lens because it focuses light
blind spot
no light sensitive cells so you can’t see from there
hyperopia
eye is too long so you can’t see close up
Myopia
eyes are squished so you can’t see far away
lens is used to correct myopia
the correct lens to use for myopia is a concave lens
lens used to correct hyperopia
The correct lens for hyperopia is convex
lens vs. mirror
lens is when light can pass through and a mirror is when light reflects or bounces off of that surface
optical technology examples
VR - This helps treat lazy eye by making both eyes work by focusing on a certain thing
Glasses - This helps treat people with poor vision because when using certain lenses, the light will be directed in a certain way that helps your eye
Laser eye surgery - This helps treat poor vision by taking out the corneal tissue to fix it a bit and put it back in the eye to improve it
