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:
Bart can travel 130 miles in 2.5 hours with this rate
Explanation:
Bart travels 52 miles per hour
For 2.5 hours first find for two hours and then for half hour. finally add this two and half hour to get for 2.5 hours.
2.5 hours=2 hours + half hour
2 hours= 1 hour × 2
= 52 miles × 2 = 104 miles
half hour= 1 hour ÷ 2
=52 miles ÷ 2 = 26 miles
2.5 hours = 104 miles + 26 miles
= 130 miles
