What is the function of the diaphragm on a microscope?
It has different sized holes and is used to vary the intensity and size of the cone of light that is projected into the slide
What is the shine of tungsten?
Tungsten shines for the same reason that any other metal shines; the metallic bond creates an electron cloud which readily reflects light.
When white light shines on a green leaf why do you see green?
our eyes detect the green light that is reflected off the leaf
What are the steps involved in focusing a compound light microscope?
1. Turn on the illuminator. When using the dimmer, it is best slowly increase the light intensity as the lamp heats up quite quickly.2.Place a slide or specimen on the stage with the sample directly above the aperture and, if possible, fasten it to the stage with the stage clips. Reminder: A cover slip is always needed to allow for the best quality image.3.Ensure the iris diaphragm is completely open, allowing the maximum amount of light to reach the slide and the lenses. Caution: Do not use the iris diaphragm to control the light, it is to control resolution and contrast - use the dimmer instead.4.Rotate the nosepiece so that theobjective lens with the lowest level of magnification is directly above the sample. Reminder: Using lower magnifications first helps to select the part of the specimen of interest and then adjust further.5.Look through the binocular eyepieces and adjust the iris diaphragm until the amount of light is satisfactory. More light is better than less light, but the comfort of the viewer's eyes should also be taken into account.6.Turn the coarse adjustment knobuntil the specimen comes into broad focus. Caution: you should not use the coarse focus with a high magnification objective for fear of the objective making contact with the slide.7.Turn the fine adjustment knob until the specimen comes into sharp focus. Caution: should not take a long time to find focus, otherwise the high magnification objective could also hit the slide. If you are having a difficult time to find focus then restart with the lower magnification objective.8.The viewer should then be able rotate the nosepiece to higher settings and bring the sample into more and more detail with a minimal amount of refocusing.-- mhayjimenez :)
What are some characteristics of tin?
Luster (reflects light rays\shines), Malliable (i.e. Can be bitting into sheets), Conductivity (i.e. Conducts electricity)
What structure on a microscope controls the amount of light that passes through the specimen?
The diaphram Is What Controls How Much Light Is Released.
What is the meaning of light source of microscope?
it is the piece located on the base that shines light on the slide that you are looking at. the light shines through diaphragm and makes the thing your looking at easier to view and more "in focus". the diaphragm is the thing that adjusts how bright the light is

What is the difference between the condenser and the iris diaphragm?
The iris diaphragm controls the amount of light passing through the slide or specimen, while the substage condenser focuses a cone of light on the slice or specimen.
Which part of a compound light microscope should a student adjust to allow more light to pass through a specimen?
the diaphragm
How are the substage condenser and iris diaphragm on a microscope different?
The iris diaphragm controls the amount of light passing through the slide or specimen, while the substage condenser focuses a cone of light on the slice or specimen.
What is the difference between using the iris diaphragm and condenser?
The iris diaphragm controls the amount of light passing through the slide or specimen, while the substage condenser focuses a cone of light on the slice or specimen.
Concentrates light onto the specimen?
The mirror, which can also be called the light source. It reflects the light.
What are the functions of a microscopes diaphragm?
The diaphragm of a microscope focuses the light into the eye piece to create optimum viewing of the specimen.
What structure on the microscope controls how much light passes through the specimen?
the diaphragm
Where is the diaphragm of a microscope located?
In the light path of the condenser beneath the specimen stage.
What is the iris diaphragm function on a compound light microscope?
the iris diaphragm controls the amount of light that passes through the stage and, consequently, through the specimen. Reducing the iris diaphragm aperture increases contrast for an image focused under high power by reducing the amount of light that both fills the objective lens and deracts around specimen edges. Opening the iris diaphragm under high magnification increases "flare", the appearance of light "washing out" an object. By decreasing the flow of light through the specimen, the iris diaphragm limits light defraction and saturation.
