Question 1: Explain why the eye must use accommodation. That is, why does the eye change its lens's focal length to see different objects? Reference the thin lens equation in your response.
Question 2: Explain which kind of lens (converging or diverging) fixes farsightedness and why it does so. Include a drawing or description of a ray diagram to support your answer.

lenght f1=40 cm. On the other side of the lens, there is a
diverging lens of focal lenght f2=4 cm, seperated from the first
lens by a distance of 36.9 cm.

There are three types of conditions by which the eye can not focus properly; myopia, hyperopia and astigmatism. Here we will explore only myopia and hyperopia. In myopia (for various reasons) the image within the eye focuses on a point in the vitreous humor and not in the retina. This causes the eye to be unable to correctly focus on distant objects. In hyperopia (for various reasons) the image focuses on a point farther away than the retina outside the...

Part II: Corrective Eyeglasses Not everybody can adjust their eyes to be able to see both distant and nearby objects clearly. In a normal eye, light from a distant object forms a sharp image on the retina. In a far-sighted eye, light from a distant object converges too gradually and would form a sharp image behind the retina (of course the retina gets in the way, and thus a blurry image hits the retina). In a near-sighted eye light from...

Don't quite get questions 1-6
For lenses in combination, the image for the first lens is the object for the second. The ray tracing diagram below shows how the rays travel through the system from object to first image/second object and then to second image. The first ray trace gives the location and size of the first image. A second ray trace is performed to find where the second object (which is the first image) creates the second image. It...

*- Jordi 1. 14 points. You wish to project an image of a slide onto a screen for a slide show. The slide is initially in a holder 0.0500m from the lens and the screen is 3.00m from the lens. The image is well-focused on the screen. a. Determine the focal length of the lens used to project the image. b. Is the lens converging or diverging? How do you know? c. If you instead want to use a screen...
