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:
negative punishment
Explanation:
Punishment (positive or negative) decreases the chances that a particular behavioral reoccurs.
Handing a prison sentence to anyone that offends the laws of the state is an example of negative punishment based on available research. This is because, serving a prison sentence makes it more likely that the convict will commit the same crime again.
While many experts in criminal justice have observed that many ex-convicts tend to re-offend, the principles of positive punishment for convicts have been set out by Peter B. Wood in his paper titled "Exploring the Positive Punishment Effect Among Incarcerated Adult Offenders
"; American Journal of Criminal Justice 31(2):8-22; 2007; .
In his submission;
<em> "As the U.S. has pursued a policy of mass imprisonment for nearly three decades, now boasts the highest incarceration rate in the world and returns nearly 800,000 ex-convicts into our communities each year, more attention to this issue is called for-particularly since it could be argued that, for many offenders, criminal justice punishments promote future offending."</em>
The first thing you have to realize is that
tangent is the
slope of a curve on a given point. You can solve for the slope by finding the derivative of the given function. So:
Next use
product rule (I recommend watching videos if you're confused):
![= [sin(x)] + [x*cos(x)]](https://tex.z-dn.net/?f=%3D%20%5Bsin%28x%29%5D%20%2B%20%5Bx%2Acos%28x%29%5D)
Next substitute you x-value (π/2) into your derivative:
![= [sin( \frac{ \pi}{2} )] +[ \frac{\pi}{2}*cos( \frac{\pi}{2})]](https://tex.z-dn.net/?f=%3D%20%5Bsin%28%20%20%5Cfrac%7B%20%5Cpi%7D%7B2%7D%20%29%5D%20%2B%5B%20%5Cfrac%7B%5Cpi%7D%7B2%7D%2Acos%28%20%5Cfrac%7B%5Cpi%7D%7B2%7D%29%5D%20%20)
So our slope at π/2 is 1. Next we use our slope-form and substitute our given value and solve for y-intercept (algebra-stuff)
So we get our equation:
So our answer is E
