How does 4x on the low power equal 40 x on the microscope?
The objective lens (right above the slide stage) is 4x. The eyepiece (what you look into) is 10x. 4 times 10 = 40. Whatever the objective lens power is, you have to multiply it by the eyepiece power (usually 10x) to get the overall magnification.
What is the magnification first used to look at a slide?
you always get to draw and have fun designing houses or buildings
How to use a microscope?
1. When moving your microscope, always carry it with both hands (Figure 1, below). Grasp the arm with one hand and place the other hand under the base for support.2. Turn the revolving nosepiece so that the lowest power objective lens is "clicked" into position (This is also the shortest objective lens).3. Your microscope slide should be prepared with a coverslip or cover glass over the specimen. This will help protect the objective lenses if they touch the slide. Place the microscope slide on the stage and fasten it with the stage clips. You can push down on the back end of the stage clip to open it.4. Look at the objective lens and the stage from the side (Figure 2) and turn the coarse focus knob so that the objective lens moves downward (or the stage, if it moves, goes upward). Move it as far as it will go without touching the slide!5. Now, look through the eyepiece and adjust the illuminator (or mirror) and diaphragm (Figure 3) for the greatest amount of light.6. Slowly turn the coarse adjustment so that the objective lens goes up (away from the slide). Continue until the image comes into focus. Use the fine adjustment, if available, for fine focusing. If you have a microscope with a moving stage, then turn the coarse knob so the stage moves downward or away from the objective lens.7. Move the microscope slide around so that the image is in the center of the field of view and readjust the mirror, illuminator or diaphragm for the clearest image.8. Now, you should be able to change to the next objective lenses with only minimal use of the focusing adjustment. Use the fine adjustment, if available. If you cannot focus on your specimen, repeat steps 4 through 7 with the higher power objective lens in place. Do not allow the objective lens to touch the slide!9. The proper way to use a monocular microscope is to look through the eyepiece with one eye and keep the other eye open (this helps avoid eye strain). If you have to close one eye when looking into the microscope, it's ok. Remember, everything is upside down and backwards. When you move the slide to the right, the image goes to the left!10. Do not touch the glass part of the lenses with your fingers. Use only special lens paper to clean the lenses.11. When finished, raise the tube (or lower the stage), click the low power lens into position and remove the slide.12. Always keep your microscope covered when not in use. Dust is the number 1 enemy!
What you want to look at under a microscope is put on one of these?
A slide.
What should be done when you are finished using a microscope?
AnswerYou should remove slide, retun scope to low power, turn off light, clean the lens(if asked) and put it away.
Why should you look to the slide before you lower the objective of your microscope?
so the objective lens will not touch the slide.
Which lens should you use to first look at a slide on a microscope?
The lens that you should use to first look at a slide on a microscope is a low power lens then move on to a higher power for more clarity.
Which lens on a microscope should you use first to look at a slide?
The lens that you should use to first look at a slide on a microscope is a low power lens then move on to a higher power for more clarity.
Why should you never lower the body tube of a microscope while looking through the eyepiece?
As I learned the hard way if you are adjusting the body of the scope while looking through the lens it is very easy to exceed the pressure threshold of a plate and crack it, destroying your sample and all your hard work. Move the slide and scope into place then look through the lens for fine adjustments.
Why is it essential that always focus away from object when looking into microscope?
In the end you will have to look into it, but at the start, when everything is far out of focus there is a real danger that as you try to find the focus you will grind the lower (objective) lens into the object, possibly destroying it, and damaging the lens at the same time.
Why should you never look at a wet mount slide with a oil immersion lens?
Wet mounts are not attached to the slide, it is "floating". If you use an oil immersion lens, you have to put a drop of oil on the slide cover so the light can correctly focus. The oil will cause the slide cover to stick to the end of your Oil immersion lens. When you focus the field of focus will stay the same since the slip cover is stuck to the lens. When you go to change objectives, the cover will travel with your oil immersion lense.
How do you replace the corner lamp lenses on a 1998 Dodge Ram pickup?
Remove the bulb/wire going into the back of lens from under the hood. Then look close around the lens and there is one screw you must remove then the complete lens will slide out moving it foward. Pay close attention when replacing there is a track/grove the new lens must slide into. Good Luck..
What happens if you move coarse adjustment knob away from you?
By doing this, it will either rise or lower the objectives to the slide to get a better look at what is n the slide.
The power of the ocular-lens on a microscope?
An ocular lens is the top part of a microscope it is the eyepiece that you look through. The ocular lens is there it magnify whatever if being viewed. It can be different strengths base on the size power of the lens.
What did Leeuwenhoek first use the micro lens for?
to look in to a slice of cork
Why must you be careful when you are focusing with a high power lens?
When you are focusing the high power objective lens, you might damage the lens if you adjust it too closely and/or damage the object/specimen you are observing. To avoid this, look to the side of the microscope when adjusting the coarse knob to make sure the high power objective lens isn't too close.:)
How can you get a specimen under a microscope to focus under the higher powered lenses without crashing the slide?
Look sideways at the slide table. SLOWLY lower the tube until it just touches the slide on the slide table. Then look through the eyepiece and SLOWLY focus BACKWARDS. That's your best bet.
