• Total Magnification- is controlled by duplicating the eyepiece power by the target focal point set up. This is usually in 10x mag. 3. Define Resolution. • Resolution- is the briefest separation between two separate focuses in a magnifying lens’ field of perspective that can in any case be recognized as unmistakable substances. 4. What is the function of the diaphragm on the microscope? • The diaphragm reduces the light from under the stage which can improve the image and it controls

Telescopes Hans Lippershey (1570 - September 1619) was a Dutch lens maker. Lippershey is believed to be the first to apply for a patent for his design‚ a few weeks before Jacob Metius (a Dutch instrument maker and optician)‚ and making it available for general use in 1608. The telescope invented by Lippershey was composed of a convex and a concave lens‚ as this construction did not invert the image and had only a magnification of just 3x. Galileo’s telescope improved the original Dutch telescopes

certain distance appear out of focus or blurry. Objects appear out of focus because those images are not projecting correctly on retina. The best treatment available for myopia are corrective lens that can manipulate those projections so that the images hit the retina where they’re supposed to hit. The corrective lens has a concave side that spread the light rays apart; which makes the images seem closer to the individual (Martini et al.‚ 2018‚ p. 569). 3.

Lab #1 ‐ Introduction to the Microscopy & Observation of Prokaryotic and Eukaryotic Cells Introduction Many of the cells and organisms that you will be studying are at the lower limits of visibility of light microscopes; therefore‚ it is extremely important that you attain critical lighting and focussing. It is also important to handle the microscope competently to avoid damaging either the microscope or the preparation you are studying
