If the ocular of your microscope is 10x and your objective that you are viewing your specimen under is 10x‚ what is the total magnification? To find the total magnification‚ you will multiply the ocular of your microscope by your objective. This results in the total magnification being 100x. 3.How does the light change on the compound microscope? Light on the compound changes from adjusting the iris diaphragm 4.What is the magnification of the ocular? The magnification of the ocular is 10x

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.

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

light to magnify the image (Figure ). They have a larger diameter lens called the objective lens and a small lens called an eyepiece. Good refracting telescopes utilize multiple lens systems to correct for color aberrations. Chapter discusses lenses in the section on “Stations for Sight”. Reflecting Telescopes Reflecting telescopes utilize one or more concave mirrors for the objective lens to condense the light and a small lens called an eyepiece.

resulting in an image that your naked eye would ordinarily see if looking at the slide. The image is then magnified by the lower (objective) lens. The objective lens flips the image and magnifies it by bending the light. The light is bent as it passes through the convex surface on either side of the lens material. The eyepiece acts as a weaker version of the objective lens by flipping the image again and magnifying it further. Compound microscopes are used most commonly to

After preparation of the slide and microscope‚ carefully place the slide onto the microscope stand. Looking from eye-level of the stand‚ lower the tube using the coarse focus know until the end of the objective lens is just about the slide (ensure you do this with care as to not break the slide).

Spherical Mirrors A spherical mirror is a mirror which has the shape of a piece cut out of a spherical surface. There are two types of spherical mirrors: concave‚ and convex. These are illustrated in Fig. 68. The most commonly occurring examples of concave mirrors are shaving mirrors and makeup mirrors. As is well-known‚ these types of mirrors magnify objects placed close to them. The most commonly occurring examples of convex mirrors are the passenger-side wing mirrors of cars. These type of mirrors
