What is the space between the objective and the slide on a microscope?
The space between the objective lens and the slide on a microscope is called the working distance. It is important because it allows for proper focusing and manipulation of the specimen without touching the lens. The working distance varies depending on the magnification and type of objective lens being used.
Once focus is achieved at one magnification a higher power objective lens can be rotated into positon without fear of striking the slide true or false?
True. Once focus is achieved with a lower magnification objective lens, a higher power objective lens can be rotated into position without fear of striking the slide because the working distance between the lens and the slide increases with higher magnification lenses.
Which objectives focuses closest to the slide?
The slide emphasizes the objective of increasing market share through aggressive marketing strategies and product promotions to attract new customers and retain existing ones. It also highlights the goal of expanding into new international markets to drive growth and profitability for the company.
Initial focusing of any slide is done under the?
The initial focusing of a microscope slide is done under the lowest magnification objective lens, known as the scanning objective lens. This allows for a wider field of view and easier location of specific structures or areas of interest on the slide.
What are the definition of different parts of microscope?
Eyepiece: The part of the microscope where the viewer looks through to see the specimen. Objective lenses: These are the lenses closest to the specimen and are used to magnify the image. Stage: The platform where the slide with the specimen is placed for viewing. Condenser: A lens that focuses light onto the specimen for better clarity and resolution.
What objective focuses closest to slide?
The oil immersion lens @100x
What is the lens closest to the slide on a microscope called?
The objective lens
If you use the coarse-adjustment knob to focus on an object with the high-power objective what problems will you encounter why?
Using the coarse-adjustment knob with the high-power objective can result in the objective lens getting too close to the slide, potentially damaging the lens or slide. This can also lead to the objective lens hitting the slide, causing a loss of focus and potential damage to both the lens and the slide.
What is the space between the objective and the slide on a microscope?
The space between the objective lens and the slide on a microscope is called the working distance. It is important because it allows for proper focusing and manipulation of the specimen without touching the lens. The working distance varies depending on the magnification and type of objective lens being used.
Which part of the microscope is used to bring the image of an object on the slide into focus when under the high power objective lens?
The fine adjustment knob is used to bring the image of an object on the slide into focus when under the high power objective lens. This knob allows for precise focusing by making small adjustments to the distance between the objective lens and the specimen on the slide.
Which of the objectives comes closest to a specimen and is most likely to break a slide if proper precautions are not taken?
The oil immersion objective comes closest to the specimen and is most likely to break a slide if proper precautions are not taken. Oil immersion objectives require the addition of immersion oil between the objective lens and the slide to improve resolution, and without the correct amount of oil or if the slide is not handled carefully, it can lead to damage or breakage of the slide.
Which of the objectives comes closest to specimen and is most likely to break a slide if proper precautions are not taken?
The high power objective lense will most likely break the slide. You need to use coarse adjustment on the low power objective lens.
Once focus is achieved at one magnification a higher power objective lens can be rotated into positon without fear of striking the slide true or false?
True. Once focus is achieved with a lower magnification objective lens, a higher power objective lens can be rotated into position without fear of striking the slide because the working distance between the lens and the slide increases with higher magnification lenses.
What should be in place when the first attempt is made to focus on an object on a slide?
Before attempting to focus on an object on a slide, ensure the slide is centered, the objective lens with the lowest magnification is in place, and the stage is at its lowest position. Start by using coarse focus adjustment to bring the object into view, and then switch to fine focus to sharpen the image.
Why can't the objective lenses touch the slide?
The objective lenses should not touch the slide because doing so can lead to scratches on the lens or slide, affecting the quality of the image. Additionally, touching the slide with the objective lens can potentially damage the specimen being viewed. Maintaining a small distance between the lens and the slide ensures proper focus and clarity in the image.
Which objectives focuses closest to the slide?
The slide emphasizes the objective of increasing market share through aggressive marketing strategies and product promotions to attract new customers and retain existing ones. It also highlights the goal of expanding into new international markets to drive growth and profitability for the company.
Why is it better to focus the microscope upward rather than downward?
Focusing the microscope upward is better because it allows for easier manipulation of the fine focus knob, which typically moves the stage closer to the objective lens. This minimizes the risk of crashing the objective lens into the slide, which can damage both the lens and the slide. Additionally, focusing upward helps prevent accidental contact between the objective lens and the specimen, reducing the chances of smudging or contaminating the lens.
