Homework Answers
Right answer- Pupil; iris
Explanation-Whenever a light comes into our eyes by the Pupil, our Iris always controls the intensity of that light by controlling our Pupil’s size. Whenever the bright light comes into our eyes this iris tries to close our pupils or tries to decrease the size of pupil so that the Pupil faces less amount of light.

Problem 4 In problem set 9, we briefly looked at how the intensity of light reaching the retina is strongly influenced by the pupil. In front of the pupil is the cornea and just behind is the lens, both of which work together to direct and focus light in the eye. Light first enters the eye through the cornea, is bent through the pupil, and then moves through the lens which is controlled by muscles...

An object is placed 9.10 cm in front of the cornea. (The cornea is thin ans has approximately parallel sides so that the reflection that occurs as light travels from air to cornea to aqueous humor is essentially the same as though the aqueous humor were directly in contact with the air. The aqueous humor has index of refraction n = 1.34 and the radius of curvature of cornea is 7.8 mm.) (a) What is the image distance for the...

In humans, the presence of a fissure in the iris is regulated by a recessive gene tied to sex. From a couple between two normal people a daughter was born with the mentioned character. The husband files for divorce on the grounds of his wife's infidelity. Explain the mode of inheritance of character and the conditions under which the lawyer of the husband can use the birth of the affected daughter as proof of infidelity.

Why do we need the cornea and the lens, if both serve to refract light ? A) because refraction is only effective when light travels between media of equal density, such as the aqueous and vitreous humors B) Because light must be bent twice in order to flip the image C) While the cornea has greater refractive power, the lens can adjust the degree of secondary refraction according to where objects appear relative to the viewer D) While the lens...
