Light waves are transmitted across the cornea and enter the eyes through the pupil.
<h3>
FURTHER EXPLANATION</h3>
The eyes and the brain are important in helping people see. Light passes through the eyes and this light gets transformed into electrical signals which are sent to the brain that helps make sense of the object that is seen.
<h3 /><h3>How People See</h3>
- Light is incident on an object (or strikes an object). Some of it get absorbed, some are reflected into a human's eye.
- Light that bounces off the object is transmitted across the cornea, the transparent outer layer of the eye. It refracts the light and makes things look sharp and clear.
- Then the light enters the pupil which is the opening in the eye controlled by the iris or the colored part of the eye. The iris changes the size of the pupil and controls the amount of light that enters the eye. When there is bright light, the pupil becomes smaller. In dim light, the opposite happens and the pupil becomes bigger.
- At the back of the pupil is the lens which again helps focus the light. Its shape changes depending on the distances of the objects that is being looked at.
- The light rays are focused by the lens so that they all converge in the retina which is at the back of the eye. The retina has many specialized cells which are sensitive to light. These cells transform light energy into electrical signals or nerve impulses which form a rough inverted image of the object the person is looking at.
- The electrical signals travel to the brain through the optic nerve. The brain turns the image upright and adds more detail to the vision.

Answer:
Political appointments are short-lived in order to prevent autocracy, tyranny, and clinging on to power.
Explanation:
Power corrupts and absolute power corrupts absolutely. Humans have a tendency to be intoxicated by power. This is why most political positions run for just a few years after which the people can determine through voting on whether they will continue with the appointee or elect another person. The presidential and senatorial sectors of the United States democracy follow this system.
Presidents are allowed 4 years in office after which another election is conducted to determine their remaining or being removed. This prevents tyranny and the imposition of the opinions of a few against the majority.
