The total magnification of a compound microscope is calculated by multiplying the magnification of the ocular lens (usually 10x) with the magnification of the objective lens. If the lowest power objective has a magnification of 4x, then the total magnification would be 40x (10x * 4x).
The letter "e" under a low power objective (LPO) typically appears magnified 10 times its actual size, as the LPO usually has a magnification of 10x. If you're using an additional eyepiece that also magnifies by 10x, the total magnification would be 100x. The exact appearance can vary based on the specific microscope used and its settings.
When focusing on a specimen under high power, you should use the fine adjustment knob. The coarse adjustment knob is typically used only under low power to prevent damage to the slide or objective lens. The fine adjustment allows for precise focusing, which is crucial at high magnifications to achieve a clear and sharp image of the specimen. Always ensure that you start with the lowest power objective before switching to high power for safety.
To determine the magnifying power of the eyepiece when a cell is observed at 200x under high power objective (HPO), you can use the formula: Total Magnification = Eyepiece Magnification × Objective Magnification. If the HPO magnification is typically 40x, then the eyepiece magnification would be 200x ÷ 40x = 5x. Therefore, the magnifying power of the eyepiece used is 5x.

Under a low power objective, the letter "e" would appear larger and more defined compared to a higher magnification. It may appear clearer and easier to discern the details of the letter.
low power objective lens to locate and focus on the specimen before moving to higher magnifications.
The total magnification of a compound microscope is calculated by multiplying the magnification of the ocular lens (usually 10x) with the magnification of the objective lens. If the lowest power objective has a magnification of 4x, then the total magnification would be 40x (10x * 4x).
If you completely lose focus while viewing a specimen under high power, you should first move the fine adjustment knob in both directions to try and regain focus. If that doesn't work, switch back to a lower magnification objective lens, refocus the specimen, and then switch back to the high power objective to try focusing again.
When viewing a slide under oil immersion, it is best to use the 100x objective lens. This high-power lens allows for greater magnification and resolution, making it ideal for observing fine details in the specimen. The use of immersion oil helps to reduce refraction of light and improves image clarity by providing a medium with a similar refractive index to glass.

When viewing a specimen under the microscope, you should always start with the lowest magnification objective lens. This allows you to locate and focus on the specimen before moving to higher magnifications for a closer look.
