How do we see colored objects
How do we see colored objects
Light strikes them and the color you see if reflected and all the rest are absorbed
How do we see white objects
How do we see white objects
Light strikes them and all colors are reflected
How do we see black objects
How do we see black objects
Light strikes them and no colors are reflected, they are all absorbed
What are the three types of materials that light can interact with
What are the three types of materials that light can interact with
Transparent, Translucent and Opaque Materials
What happens when light strikes an opaque material
What happens when light strikes an opaque material
No light passes through, it is either reflected or absorbed
What happens when light strikes a transparent material
What happens when light strikes a transparent material
All light passes through
What happens when light strikes a translucent material
What happens when light strikes a translucent material
Some light passes through but not all; light is scattered
When light strikes an object it can either be _________, _________ or ______.
When light strikes an object it can either be _________, _________ or ______.
Reflected, Absorbed or Transmitted
What are the 6 main parts of the eye that process light
What are the 6 main parts of the eye that process light
Cornea, Iris, Pupil, Lens, Retina, Optic Nerve
Which two parts of the eye bend light as it passes through
Which two parts of the eye bend light as it passes through
The cornea and the lens
What is the difference between the iris and the pupil
What is the difference between the iris and the pupil
The iris is the colored part that controls how much light enters; the pupil is the black hole in the eye
What is the job of the optic nerve
What is the job of the optic nerve
To process and send signals of light to the brain
