magnification, 1) the ocular, or eyepiece lens that one looks into and 2) the objective lens, or the lens closest to the object.” The source said that usually you will find 3 or 4 objective lenses on a microscope. Moreover, the source said that you would need a relatively sophisticated microscope with an Abbe condenser to have a good resolution at 1000x.

in the eye and forms a sort of cloud in the natural lens of the eye that could eventually lead to blindness if not treated properly. This type of cataract is different from most cataracts, since congenital cataracts is present in an individual since birth, meaning that it was most likely inherited from the parents. The way that it is inherited is by some sort of abnormality, which would transpire during the making of the proteins that make the lens clear. There are many different

1. What is aperture priority mode? When might you use this mode on a camera? Aperture priority mode lets you control the aperture while the camera adjusts the rest of the settings. You would use this mode when you want to control the depth of the field and there is lots of light. 2. What is depth of field? How can you adjust the depth of field in a photograph? The depth of field is the focus amount in the photo. You can adjust the field depth by aperture. A larger aperture creates a smaller field

tissue from the eye called lens. The lens is located behind the iris and the pupil, this tissue is fundamental in order to complete the visual process. The lens is a clear part of the eye that helps to focus light or images on the retina, working like a camera lens. Cataracts produce a clouding on the lens affecting the vision of the person. Most of them are commonly cause by aging, however they can be develop on young people as well, but how are cataracts develop? The lens is made of water and proteins;

and Fibers Sample Observation Chart Unknown samples of Hair and Fibers Procedure A compound microscope is provided. Carefully notice the functions of each part of the microscope. It is consisted of eyepiece, eyepiece tube, aperture, objective lens, Iris diaphragm, illuminator and fine focus knob. The sample are put on stage to view it carefully by adjusting the aperture and focus of the microscope. Part A In this

Summarise the differences between how the Light Microscope, Transmission Electron Microscope and Scanning Electron Microscope work; Evaluate the advantages and disadvantages of each type of microscope. The three different types of microscope all work very differently. They all have limitations as to what can and cannot be seen through them and two key factors as to why this is are magnification and resolution. Magnification determines how closely we can look at the object, whereas resolution presents

Microscopy and the Metric System Margaret E. Vorndam, M.S. Version 42-0090-00-01 Lab Report Assistant This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports

(ERT Task Sheet, 2015). An average above surface camera cannot simply be made waterproof using a camera housing in order to operate effectively underwater. There are special demands created by various aspects of the marine environment for example, the lens must be designed specifically to recorrect the distortion created by refraction and strobes must be placed away from the camera to avoid backscatter. Refraction mainly occurs when underwater photographers use a flat port (Deep Ocean Diving - Underwater

Microscopy is a practical field for using microscopes to view object that cannot being seen with the naked eye or object that contained by the resolution range of the normal eye. There are two fundamentally different types of microscope. 1. ELECTRON MICROSCOPE:- Consist of electromagnetic lenses to focus a beam of light . - Having magnification power up to 200000. LIGHT MICROSCOPE:- consist of a single or a series of glass lenses to focus light in order to form an image. - Having maximum ability
