How do you determine the magnification of a specimen?
Multiply the magnification of the eyepiece by the magnification of the objective lens to produce total magnification. For example, a 10X ocular lens and a 40X objective lens will produce a total magnification of 400X (10 x 40 = 400).
What magnification is 40x objective?
400x magnification
A microscope’s total magnification is a combination of the eyepieces and the objective lens. For example, a biological microscope with 10x eyepieces and a 40x objective has 400x magnification.
What is the meaning of 100x magnification?
Total magnification = 10 X 10 = 100X (this means that the image being viewed will appear to be 100 times its actual size).
What should the magnification of a sample be?
Sample objective magnifications. The high-powered objective lens (also called “high dry” lens) is ideal for observing fine details within a specimen sample. The total magnification of a high-power objective lens combined with a 10x eyepiece is equal to 400x magnification, giving you a very detailed picture of the specimen in your slide.
What is the magnification of a compound microscope?
With a compound microscope, the magnification is the product of both lenses, so if microscope has a 10x eyepiece and an 40x objective, the total magnification is 400x. Magnification is defined as the ratio of the size of the image to the size of the object.
How to calculate the total magnification of a lens?
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\imes 4 = 40. The total magnification of 40 means that the object appears forty times larger than the actual object.
What is the relationship between size and magnification?
Magnification is defined as the ratio of the size of the image to the size of the object. The relationship between these three values can be shown using the equation triangle to the right, which offers a quick way of rearranging the values in order to derive related formulas.
