What else can I help you with?
Say you were observing a specimen on the low power objective when you switch to high power the specimen is no longer visible why?
The high power objective has a shorter focal length and narrower field of view compared to the low power objective. This can cause the specimen to move out of the field of view when switching from low to high power, especially if it was not centered properly. Adjusting the mechanical stage to re-center the specimen or refocusing the microscope may help bring the specimen back into view on high power.
What are the advantages of knowing the diameter of the field of view at a given magnification?
Knowing the diameter of the field of view at a given magnification helps in estimating the size or distance of objects being viewed under the microscope. It also aids in calculating the area being observed and comparing the relative sizes of different objects in the field of view. Additionally, it provides important information for accurately measuring and identifying microscopic specimens.
The ordinary light microscope is called a bright-field microscope because?
the object appears light on a dark background
When electrons are rearranged in an object by an electric field the object is charged by what?
When electrons are rearranged in an object by an electric field, the object is charged by gaining or losing electrons. If an object gains electrons, it becomes negatively charged, and if it loses electrons, it becomes positively charged.
Does the space around an electrically charged object is an electric field?
yes the space around a electrically charged object is known as electric field......
How do we know that an object is a magnetic object?
An object is considered a magnetic object if it is attracted to a magnet or if it has its own magnetic field that can interact with other magnetic fields. This can be tested by observing if the object is drawn toward a magnet, or by using a compass to detect any magnetic field it may produce.
Why is an object no longer in view as one switches from low power to high power using the microscope?
At a higher power the field of view is smaller and the object may no longer be in the field of view. Or it may have gone out of focus.
How do you switch from one magnification to another magnification in a microscope and still keep the same object in you field of view?
To switch between magnifications on a microscope and keep the same object in view, first center the object in your field of view at the lower magnification. Then, without moving the slide or stage, rotate the nosepiece to change to the desired higher magnification. The object should remain centered in your field of view at the new magnification. Adjust the focus as needed.
How does a magnet with an on-off switch work?
A magnet with an on-off switch works by controlling the flow of electricity to the magnet. When the switch is turned on, electricity flows through the magnet, creating a magnetic field. This magnetic field attracts or repels other magnetic objects. When the switch is turned off, the flow of electricity stops, and the magnetic field disappears, causing the magnet to no longer attract or repel objects.
What is another term for fraunhofer diffraction?
Another term for Fraunhofer diffraction is far-field diffraction. This type of diffraction occurs when the distance between the diffracting object and the screen observing the diffraction pattern is much greater than the dimensions of the diffracting object.
What is the largest unit of a database?
is a Field.
The mass of an object in a gravitional field is called?
The mass of an object in a gravitational field is called the object's "mass".The presence or absence of a gravitational field has no effect on the mass.
Why is it believed that the Earth's magnetic field has reversed its polarity in the past?
By observing magnetic rocks in geological deposits.By observing magnetic rocks in geological deposits.By observing magnetic rocks in geological deposits.By observing magnetic rocks in geological deposits.
What is an object field?
what is an ole object fied
What is true about an object pulled inward in an electric field does it have negative charge object has charge of different field object has neutral charge or object has a charge same field?
An object being pulled inward in an electric field typically implies the object has a positive charge, as oppositely charged objects are attracted to each other. If the object has a negative charge, it would be pushed away from the field. If the object has a neutral charge, it would not experience any force in the field.
How dense can something get before a gravitational field develops?
An object needs to surpass the Chandrasekhar limit, approximately 2.0 × 10^17 kg/m^3, to develop a gravitational field. This limit represents the point at which electron degeneracy pressure can no longer support the object against gravitational collapse, leading to the formation of a neutron star or black hole.
An increase in magnification causes?
The increase in magnification cause a decrease in the field of view.
