What happens to the light intensity as you change magnification of the objective light?
Magnification focuses light into a smaller area making it appear more intense.
When you move to a higher magnification do you see more or less of the specimen?
With higher magnification you can observe bigger.To see clearly resolution also should be high.
Are light microscopes more powerful than electron microscopes?
Yes, electron microscopes have a much higher possible magnification than compound light microscopes. An electron microscope is capable of 10,000,000 times magnification, whereas a good compound light microscope is capable of 1,000 - 2,000 times magnification.
What microscope would be used to study a specimen smaller than 0.2 micrometers?
The maximum magnification of a light microscope is 2000x. Anything requiring more than 2000x magnification requires an electron microscope.
Why is locating an object more difficult if you start with high power objective than with the low power objective?
When using a microscope, you are magnifying the area under the lens by however many times the magnification is on your lens. On low power the area expanded by the lens is smaller than on high magnification. When on low power more is visible and there is less area to search for your given object under the microscope. I recommend finding the object on low magnification, and then switching to high once you have found it.
Why is it one needs more illumination when using the higher levels of magnification?
It's actually simple: The more the magnification, the smaller a "picture" of the available light you are getting - hence the more magnification, the darker the image looks. It works the same way with an astronomical telescope: The more magnification you use (assuming the objective lens doesn't change) the dimmer the object gets. To put it another way - there is a big difference between how high a magnification you are using, and how much light is reaching your eye.
What happens to the light intensity as you change magnification of the objective light?
Magnification focuses light into a smaller area making it appear more intense.
Is it more desirable to increase or decrease light when changing to a higher magnification using a compound microscope?
It is more desirable to increase light when changing to a higher magnification using a compound microscope as the lens require more light. With proper lighting , it is easier to see specimen details as the lens aperture decreases with higher magnification.
As the magnification used in microscope increases is more or less illumination needed Explain your answer?
As the magnification increases, more light is needed. This is because the size of the hole of the lens is smaller.
Can you Define magnification in an optical telescope?
Allows you to gather more light from a distant object.
When you move to a higher magnification do you see more or less of the specimen?
With higher magnification you can observe bigger.To see clearly resolution also should be high.
Which is more important in telescopes magnification or ability to gather light?
It is a balance of both. Without the magnification, we wouldn't be able to see very far. But without the ability to gather and make out trace amounts of light, we wouldn't be able to make anything out while looking through the magnification.
Are light microscopes more powerful than electron microscopes?
Yes, electron microscopes have a much higher possible magnification than compound light microscopes. An electron microscope is capable of 10,000,000 times magnification, whereas a good compound light microscope is capable of 1,000 - 2,000 times magnification.
When you look at objects under high magnification what happens to the brightness?
get more lighter or gets darker
What microscope would be used to study a specimen smaller than 0.2 micrometers?
The maximum magnification of a light microscope is 2000x. Anything requiring more than 2000x magnification requires an electron microscope.
How is the total magnification of a microscope determined?
Total magnification is determined by multiplying the magnification of the ocular lens by that of the objective lens. Compound microscope that uses more than one lens to direct light through a specimen mounted on a glass slide.
Is magnification more play role or resolution?
Magnification
