AP PSYCHOLOGY

Detailed explanation-1: -Pupil: The pupil is the opening at the center of the iris through which light passes. The iris adjusts the size of the pupil to control the amount of light that enters the eye. Retina: The retina is the light-sensitive tissue at the back of the eye.

Detailed explanation-2: -First, light passes through the cornea (the clear front layer of the eye). The cornea is shaped like a dome and bends light to help the eye focus. Some of this light enters the eye through an opening called the pupil (PYOO-pul). The iris (the colored part of the eye) controls how much light the pupil lets in.

Detailed explanation-3: -The iris controls widening and narrowing (dilation and constriction) of the pupil. Cornea: the transparent circular part of the front of the eyeball. It refracts the light entering the eye onto the lens, which then focuses it onto the retina.

Detailed explanation-4: -Ciliary muscles functions to change the focal length of the element in the human eye so that it can focus on two different objects at a different distance.

Detailed explanation-5: -The pupil is an adjustable opening that controls the intensity of light permitted to strike the lens. The lens focuses light through the vitreous humor, a clear gel-like substance that fills the back of the eye and supports the retina.
