A lens of short focal length has a greater power (than a lens of large focal length)
The oil immersion lens or objective has power 90X-100X and an eyepiece lens generally in light microscope comes with 10X so total magnification of oil immersion lens is 100X10 = 1,000
The coarse adjustment knob on a microscope should never be used with the high-power objective lens. This can cause damage to both the lens and the slide being viewed. Instead, it is best used with the low-power or scanning objective lens for initial focusing.
A high power objective lens 40x refers to a microscope lens that magnifies the specimen 40 times its actual size when viewed through the microscope. This lens is used for detailed observation of fine structures and requires careful focusing due to its high magnification level.
The low power objective lens on a microscope typically provides a magnification of around 10x. This lens is used for initial focusing and locating objects on a slide at a lower magnification before switching to a higher magnification lens. It offers a wider field of view compared to higher magnification lenses.
The nosepiece of a microscope holds multiple objective lenses, each with different magnification levels that range from high to low power. Rotating the nosepiece allows you to switch between these objective lenses to adjust the magnification of your specimen.
A high power objective in a microscope is a lens that provides high magnification of the specimen being viewed. It typically magnifies the image by 40x to 100x, allowing for detailed observation of fine structures. High power objectives are used for examining smaller details and are typically used after lower magnification objectives.

A high power objective lens is a microscope lens with a high magnification level, used for viewing specimens in fine detail. It allows for closer inspection of specific features or structures of the specimen.
Which of the following is a correct procedure for the operation of a microscope? First, put the specimen into focus using a low power lens, then switch to a lower power lens if needed.Remove and add slides while the high power lens is selected.First, put the specimen into focus using a low power lens, then switch to a higher power lens if needed.Use the fine focus knob with the low power lens and use the coarse focus knob with the high power lens
the high power lens uses a lot of light scorce so it could burn your eyes
The oil immersion lens or objective has power 90X-100X and an eyepiece lens generally in light microscope comes with 10X so total magnification of oil immersion lens is 100X10 = 1,000
The objective lens that focuses closest to the slide is 100x, it has the longest lens so the highest power. Be careful not to crack the slide and make sure you use oil if it is an oil immersion lens.
So you do not crack the high power objective lens - this lens is very fragile and expensive.
A lens with a power of 19.5 diopters would be considered a strong prescription lens for correcting vision. It indicates that the lens has a high refractive power, which is often needed for individuals with severe nearsightedness or farsightedness.
The coarse adjustment knob on a microscope should never be used with the high-power objective lens. This can cause damage to both the lens and the slide being viewed. Instead, it is best used with the low-power or scanning objective lens for initial focusing.

The lens with the greatest (positive) curvature. The lens with the highest diopter.
