Answer:
<h2>The Tri-Chromtic theory</h2>
Explanation:
The Tri-chromatic theory is based on the assumption that the three classes of cone receptors sub serve the colour vision. This theory dates back to 18th century and was popular during the first half of 20th century and was often used against the opponent processes theory. It was also known as Young-Helmholtz theory of colour vision, according to this theory there are three receptors in the retina that are responsible for the perception of colour. These receptors have different sensitivity level. Blues ones are the most sensitive and the red ones the least. But to perceive the colour needs the interaction between at least two photo receptors. Then the three colours are combined to form any colour in the visible spectrum.
Vision test is the gold standard test for assessing visual function and how it responds to <u>light stimuli</u> that enter the eye and produce a sensation of light and possibly color as well.
<h3>What is a vision test?</h3>
It is a test used to determine the ability of our visual system to distinguish details clearly at a given distance and under certain conditions.
The deeper retina contains the receptors for light stimuli (photoreceptors), these tests measure the eye's ability to define details and are established as a mathematical relationship between the size of an object and the distance it is from the eye.
Therefore, we can conclude that a vision test is the gold standard test for assessing visual function and how it responds to <u>light stimuli</u> that enter the eye and produce a sensation of light and possibly color as well.

Answer:
Try to change his theory to correlate with the new observations, otherwise, discard his theory.
Explanation:
For scientist to develop a thoery, he must be able to follow the following steps:
1. Making of observation
2. List out questions relating to the object of research
3. Create hypotheses
4. Form prediction on the basis of hypotheses
5. Test the prediction
6. Perform iteration
Hence, if the predictions of the theory correlates with the results of the test, the theory will be temporarily confirmed. Otherwise, the scientist should try to change his theory to correlates or be in accordance with the new observations and, if he cannot do so, discard his theory.
