The high-power objective on a microscope is larger lens with higher magnifying power. (40x)
HIGH POWER OBJECTIVES

low power:100 small pollen grains high power:25 large pollen grains
Disadvantages of using vandergraff generators is static electric can't always be generated at a high level.
requires high pressure
the difference between the low power and high power objectives on a microscope are that the low power objective has a lesser magnification than the high power objective
Low power objective magnifies the object by 10 times, whereas high power objective magnifies 40 times. When we change from low power to high power, the object appears larger, exactly 4 times larger than low power. Low power objective covers a larger area, whereas high power covers a smaller area.
The field for the high power objective is very small, so if you do not have the organism or whatever you want to view in focus on a lower power, it may be very difficult to find on high power. Also, the lens for the higher power objectives are longer than the lower ones, which makes them closer physically to the slide that you are viewing than the lower objectives. Thus you must use the fine tuning knob to sharpen the image in high power, because you could break the slide if you use the course adjustment knob.
