The trichromatic theory has short (blue), medium (green) and long (red) wavelength. Each cone responds to a broad range of wavelengths. The ratio of the activity is across three types of cones and the more intense the light it increases the brightness of color. Opponent theory the brain perceives color on a continuum from red to green and also from yellow to blue. The mechanism for this theory is a bipolar cell excited by a set of wavelengths.
When released by the sending neuron, neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing where that neuron will generate a neural impulse. b) What is an agonist?

Purpose: When light travels through different mediums, it is being refracted. The purpose of this lab is to test Snell’s law of refraction. Hypothesis: The angles of refraction that I predicted from the angle of incidences by using Snell’s Law are below on the predicted angle Column. To obtain these values I used the index of refraction of crown glass because it is more likely close to the glass (plexiglass) that we are using. Angle of Incidence 0° 10° 20° 30° 40° 50° 60° Predicted angle of refraction 0 6.56° 13.0° 19.2° 25.02° 30.27° 34.74° Variables and Controls: Independent Variable: The angle of the light coming from the ray box or the angle of incidence Dependent Variable: The angle of refraction on the plexiglass.
We can conclude that the data are Poisson distributed. Chi-Square test of independence Problem 12.12 Use the following contingency table to determine whether variable 1 is independent of variable 2. Let α = .01 | Variable 2 | Variable1 | 24 | 13 | 47 | 58 | | 93 | 59 | 187 | 244 | Step 1 Ho: the two classifications are independent Ha: the two classifications are dependent Step 2 d.f = (r – 1) (c – 1) Step 3 α = 0.01 x 2 0.01, 3df = 11.3449 Step 4 Reject Ho if x 2 > 11.3449 | Variable 2 | Total | Variable1 | 24 (22.92) | 13 (14.10) | 47 (45.83) | 58 (59.15) | 142 | | 93 (94.08) | 59 (57.90) | 187 (188.17) | 244 (242.85) | 583
The stimulus onset asynchrony (SOA) between the two stimuli was used to compute just noticeable differences (JNDs) in milliseconds. JNDs provide an index of temporal resolution i.e. small JNDs indicate high temporal resolution. The context was manipulated to include both static and dynamic distractors. These distractor events were measured along the vertical and horizontal meridians.
These experiments are as follows, the convergence of gaze, accommodation of the sight, blind spot of the eye, mechanical stimulation of the photoreceptors, positive afterimage, negative afterimage and finally visualizing retinal blood vessels. Basically these are all proved and documented
