When light bounces off
Reflect
Why can the teacher see the student?
The light reflects of of the student into the teachers eyes through the parts of the eyes into the brain where it is decoded and produces and image for her to see the student
Glass
Mostly transmits a little reflects
Cornea
The first part of the eye that refracts the light through the pupil
Mrs. Cramer's desk
Not reflective not smooth dust causes us not to see a reflection
When light goes through something
Transmit
Why can the student see the student?
The light reflects off himself into the mirror reflects off the mirror into his eyes and the light is bright enough to register in his brain and produces and image for him
Regular mirror
All light reflects
Pupil and Iris
Iris controls the pupil making it big when its dark and small when its light. The pupil funnels the light into the lens.
Mrs. Cramers desk right after she wipes it down
Smooth and reflective because of the liquid from the wipe.
When light changes direction or bends
Refract
Why cant student see the teacher?
The light transmits through the one way mirror and reflects of the teacher transmits back through the one mirror into the students eye. The light is too weak to be decoded by the brain.
One way mirror
Equal amounts of light reflects and transmits
Lens
Focuses the light bending when something is far or flattening when an object is near. Sending the electrical signals to the retina.
Mrs. Griffith's silver Stanley (even though Starbucks cups are better )
Smooth and reflective
The phenomenon brought down in size so we can explore it
Scale model
Describe the one-way mirror
The one way mirror has a half silvering film that allows some of the light to transmit and some of the light to reflect
A calm lake
Mainly reflects
Retina and Optical nerve
The retina made up of 130 million cells picks up the electrical signal and sends them through the optical nerve to the brain.
A sanded basketball court
Rough not reflective
The process of making a mirror by putting a layer of metal on the back
Silvering
Which light is on in our phenomenon and which light is off?
The light in the room with the student is on the light in the room with teacher is off
A lake on a windy day
Does not reflect or little reflection
Brain
Translates the electrical signal and produces and image for us to see. If the light is too weak it does not produce an image
A waxed basketball court
Smooth and reflective
