Behavior of Light
How does light behave when it comes in contact with a regular mirror?
It reflects
This is the part that allows light to enter the eye, it also controls how much light enters.
The pupil
silvering
During our light lab this material reflected the most light.
A mirror
How does light travel?
In straight lines
How does light behave when it comes in contact with glass?
Most transmits, a small amount reflects
What part of the eye causes the light to focus on the retina?
The lens
when light bounces off something.
reflect
During our light lab this material transmitted the most light.
Glass
Why does the brain sometimes ignore certain light inputs and prioritize others?
The brain only processes the strongest light input.
How does light behave when it comes in contact with something opaque (like a dirt road)?
It is absorbed
This is the part that changes the light signal in to an electrical impulse.
The retina
This type of material allows light to pass through it completely.
Transparent
During our light lab this material transmitted and reflected almost the same amount of light.
One-way mirror
Why can't Pete see the teacher?
Because the light input showing her image is too weak. His brain processes the stronger signal. The one-way mirror and the light also have an impact.
What is it called when light travels between two different mediums (like air and water) and appears to bend?
Refraction
This is the part that sends an electric signal to the brain.
This type of material does not allow light to pass though it.
Opaque
When drawing the Path of light with arrors where should the arrow start?
At the light source
What are the three ways light reacts when it hits different materials?
reflects, transmits, is absorbed.
How do we see things that do not produce their own light?
We see the light from a source reflecting off things that do not produce their own light.
This is the part that process the electric signal into what we "see"
The brain
When light travels though an object.
Transmit
How does the path of light travel to your eyes so you can see your reflection on a mirror?
First the light shines on you. Then some light reflects off you and travels to the mirror. Then light reflects off the mirror into your eyes.
Why can you see yourself in a mirror, but not in a piece of glass?
The light reflects off the mirror, but it transmits though glass.
