Vision- Parts Of Eye

Question 0

Wavelength

Answer 0

Distance from the peak of one light or sound wave to the peak of the next

Question 1

Lens

Answer 1

Primary focusing structure. Produces clear image to retina. Reverses what you’re looking at

Question 2

Hue

Answer 2

Dimension of color. Determined by wavelength of light

Question 3

Retina

Answer 3

Layer of tissue at the back of the eyeball

Contains receptor rods and cones and neurons that process visual information

Question 4

Intensity

Answer 4

Amount of energy in a light or sound wave

We perceive it as brightness or loudness

Question 5

How does the eye transform light into messages and information

Answer 5

Light enters through the cornea-> passes through pupil-> behind pupil is a transparent lens that focus on incoming light and puts image on retina-> lens focussed using accommodation

Question 6

Accommodation

Answer 6

Process by which the eyes lens changes shape to focus on near or far objects on retina

Question 7

Cornea

Answer 7

Protects eye and bends light to focus

Question 8

Pupil

Answer 8

Small adjustable opening surrounded by the iris

Question 9

Rods

Answer 9

100-120 million in each eye. Respond to light and dark. Allow us to see in dim light

Question 10

Cones

Answer 10

6 million in each eye. Respond to color and fine detail. Absorb light.

Question 11

Optic nerve

Answer 11

Nerve that carries neural impulses from the eye to the brain

Question 12

Fovea

Answer 12

Central focus point in retina around which the eyes cones cluster

Question 13

Visual information processing

Answer 13

Light particle goes through outer layer or cells to rods and cones-> light energy triggers and activates bipolar cells-> then talks to ganglion cells that form the optic nerve-> nerve carries info to brain. And then thalamus distributes
