A lens of short focal length has a greater power (than a lens of large focal length)
The objective lens is found on the nosepiece of a microscope that ranges from high to low power. It is the lens closest to the object being examined.
On a typical light microscope, the low power objective lens will be shorter than the high power objective lens.
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 high-power objective lens rests very close to the slide so adjustments such as focusing (which moves the lens up and down) could potentially push the lens right through the slide. It's usually advisable to take your eyes off the eyepieces and actually get to an angle that allows you to watch the space between the lens and slide when changing to the high power to avoid breaking the slide if the lens is already too low.

The high power objective in a microscope is the largest lens in the microscope.
The objective lens is found on the nosepiece of a microscope that ranges from high to low power. It is the lens closest to the object being examined.
On a typical light microscope, the low power objective lens will be shorter than the high power objective lens.
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
when you change from low power to high power the light intensity decreases. this is because the high power objective lens is smaller than the low power lens. therefore, the high power lens lets less light through
scanning-40x low-100x high-400x
The high-power objective on a microscope is larger lens with higher magnifying power. (40x)
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
So you do not crack the high power objective lens - this lens is very fragile and expensive.
