Definition
| Sound waves are collected by the PINNA (earlobe). |
|
|
Term
|
Definition
| Sound waves go through the outer ear canal and hit a thin layer of skin called the EAR DRUM. This makes the ear drum vibrate. |
|
|
Term
|
Definition
| Next, the vibration triggers three bones called the hammer, anvil and stirrup. |
|
|
Term
|
Definition
| The bones send vibrations to a snail-like structure called the COCHLEA. |
|
|
Term
|
Definition
| The hair-like cells and liquid in the COCHLEA turns the vibrations into electro-chemicals. |
|
|
Term
|
Definition
| The electro-chemical is sent to the nerves which send it to the brain. |

| Light enters the eye through a transparent covering called the CORNEA. |
|
|
Term
|
Definition
| The light enters the PUPIL, an opening in the eyeball. |
|
|
Term
|
Definition
| After passing through the PUPIL, the light goes through the lens. This convex lens projects the light onto the lining of your eyeball called the RETINA. |
|
|
Term
|
Definition
| This image is upside-down b/c the light is refracted when it passes through the PUPIL and the LENS. |
|
|
Term
|
Definition
| Cells on the retina called ROOTS and CONES change the light into electro-signals that travel up the OPTIC NERVE. |
|
|
Term
|
Definition
| Your brain interprets these signals and turns the image right-side up. It also combines the signals to both eyes into a 3D image. |

Definition
| light reaches an object with the full color spectrum. the only that REFLECTS is the color of the object. |
|
|
Term
|
Definition
| occurs when light waves are reflected by a non-smooth surface (lightwave is separated) |
