Answer:
What is the total magnification of the ocular lens is 10x and the objective lens is 100x?
The objective and ocular lenses are responsible for magnifying the image of the specimen being viewed. So for 10X objective and 10X ocular, Total magnification = 10 X 10 = 100X (this means that the image being viewed will appear to be 100 times its actual size).
2. How many times can a specimen be magnified if it is viewed under the high power
objectives and 16x eyepiece?
Does the depth of field of the microscope increase when the magnification power of the objective lens is increased?
The depth of field is a measure of the thickness of a plane of focus. As the magnification increases, the depth of field decreases.
Step-by-step explanation:
Finding Lens Magnification
Finding the magnification of each lens requires examining the casing of each lens. On the side of the casing is a series of numbers that includes a number followed by x, as 10x. This 10x shows that the lens magnifies an object to appear ten times larger than reality. Depending on the manufacturer, this magnification number may appear at the beginning or at the end of the number sequence. To calculate total magnification, find the magnification of both the eyepiece and the objective lenses. The common ocular magnifies ten times, marked as 10x. The standard objective lenses magnify 4x, 10x and 40x. If the microscope has a fourth objective lens, the magnification will most likely be 100x.
Calculating Magnification
Once the magnification of each individual lens is known, calculating total magnification is simple math. Multiply the magnification of the lenses together. For example, if the eyepiece magnification is 10x and the objective lens in use has a magnification of 4x, the total magnification is:
10\times 4 = 4010×4=40
The total magnification of 40 means that the object appears forty times larger than the actual object. If the viewer changes to the 10x objective lens, the total magnification will be the ocular's 10x magnification multiplied by the new objective lens's 10x magnification, calculated as:
10\times 10 = 10010×10=100
Note that calculating magnification in telescopes uses a different equation than calculating magnifiction in microscopes. For telescopes, one magnification calculation uses the focal lengths of the telescope and the eyepiece.
