the pupils Iris diaphragm-controls the amount of lightreaching the condenser. The size of the iris diaphragm opening should approx- imate that of the face of the objective lens. Thus, as a general rule, the diaphragm is completely closed when liquid preparations are observed with the low-power objective, and wide open when stained preparations are observed with the oil-immersion lens using natural light. http://74.125.47.132/search?q=cache:MjyDOLz_L4AJ:www.tpub.com/content/medical/10669-c/css/10669-c_228.htm+3.+What+controls+the+amount+of+light+reaching+the+ocular+lens%3F&hl=en&ct=clnk&cd=2&gl=us
What else can I help you with?
What controls the amount of light reaching the retina?
The iris controls the amount of light reaching the retina by adjusting the size of the pupil. In bright light, the iris contracts to make the pupil smaller, reducing the amount of light that enters the eye. In low light, the iris expands to dilate the pupil, allowing more light to enter the eye.
What does the pupil in the human eye do?
The pupil controls the amount of light entering the eye by adjusting its size. In bright light, the pupil constricts to allow less light in, and in dim light, it dilates to allow more light in. This helps to regulate the amount of light reaching the retina for optimal vision.
What is the circular opening of the eye which controls the amount of light that enters the eye?
The circular opening of the eye that controls the amount of light entering is called the pupil. It dilates in low light to allow more light to enter and constricts in bright light to reduce the amount of light entering the eye.
What structure on a microscope controls the amount of light that passes through the specimen?
The Diaphragm or diaphragm control lever regulates the amount of light passing through the slide specimen on the microscope stage.
What is the function of the diafragm in a microscope?
it controls the amount of light let into the slide.
What controls the amount of light reaching the retina?
The iris controls the amount of light reaching the retina by adjusting the size of the pupil. In bright light, the iris contracts to make the pupil smaller, reducing the amount of light that enters the eye. In low light, the iris expands to dilate the pupil, allowing more light to enter the eye.
Which part of the microscope controls the amount of light?
The condenser is the part of the microscope that controls the amount of light reaching the specimen. By adjusting the condenser's aperture and height, you can regulate the amount and focus of light used for illumination in the microscope.
What part of the microscope that control the amount of light reaching the slide?
The diaphragm on a microscope controls the amount of light reaching the slide. It is located beneath the stage and can be adjusted to change the intensity and quality of the lighting.
What regulates the amount of light reaching the objective lens in a microscope?
The diaphragm or iris controls the amount of light passing through the specimen and reaching the objective lens in a microscope. By adjusting the diaphragm opening, you can increase or decrease the amount of light to optimize the image contrast and brightness.
What is 'irie'?
The colored, and muscular ring around the pupil in your eye. It narrows in bright light and widens when light is dim.It also controls the amount of light reaching the retina
What does the pupil in the human eye do?
The pupil controls the amount of light entering the eye by adjusting its size. In bright light, the pupil constricts to allow less light in, and in dim light, it dilates to allow more light in. This helps to regulate the amount of light reaching the retina for optimal vision.
What structure controls how much light passes through the specimen?
The diaphragm or iris controls the amount of light passing through the specimen in a microscope. By adjusting the diaphragm opening, the amount of light reaching the specimen can be regulated, thus providing better clarity and contrast during observation.
What two parts of a camera controls the amount of light reaching the film?
The Shutter and the Aperture are the two controls the Shutter is used to control how long the Film is exposed for and Aperture is used to control how much light is let in
What structure controls the amount of light that gets in the eye?
Iris controls the amount of light entering into the eye.
Two parts of the microscope that regulate the amount of light visible through the ocular are the?
iris diaphragm and condenser. The iris diaphragm controls the amount of light coming from the light source, while the condenser helps focus and direct this light onto the specimen. Adjusting these parts ensures optimal illumination for clearer observation.
Which structure controls how much light passes through a specimen?
The diaphragm or iris controls the amount of light passing through a specimen in a microscope. By adjusting the diaphragm, you can regulate the intensity and focus of light reaching the specimen, improving visibility and clarity during observation.
What are the parts of microscope that provide light?
The parts of a microscope that provide light are the light source (such as a light bulb or LED), the condenser lens system that focuses the light onto the specimen, and the iris diaphragm that controls the amount of light reaching the specimen.
