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.

Microscope is an indespensable tool why?
A microscope (literally ~ 'see small') is a device to aid our natural eyesight. A low power microscope (<40 times) is very useful in inspection of samples, and in dissecting small structures. Such as parts of a flower. Stereo microscopes are good in this region. From here you go up to medium power 'scopes, up to a few hundred times. You'll now be looking at the grains of sandstone and similar small items. A binocular microscope will be useful, but you'll no longer have stereo presentation. Much more than a few thousand becomes difficult for a light microscope, for your subjects themselves approach the wavelength of light in size. Beyond this, electron microscopes rule, and they may not actually look at the specimen directly. They fire a beam of electrons at the specimen, and display the results on a video screen. But you can have much more fun here, for if the electrons are sufficiently energetic, they can cause secondary emission from the sample, and analysing these emissions can identify the elements in the sample. You'll now be looking at part of an individual grain of a sandstone. And with an EM microscope it is simple to copy the picture from the video screen.
A temperature of 40 degrees Celsius is equal to what temperature on the Fahrenheit scale?
40= 104 f
How many metres are there in 40 yards?
There are 0.9144 metres in one yard. Therefore, 40 yards is equal to 40 x 0.9144 = 36.576 metres.40 yards = 36.576 metres36.57600 metres
What is 40 degrees Celsius in Fahrenheit degrees?
40 degrees Celsius is equal to a temperature of 104 degrees Fahrenheit.
What is 40 degrees Fahrenheit equal to in Celsius degrees?
40 degrees Fahrenheit is 4.4 degrees Celsius.
What is 40 to the tenth power?
40^10 is equal to 10,485,760,000,000,000.
What does 40 to the second power equal?
20
What is 40 raised to the one fifth power equal?
405 = 102,400,000
What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 40 x and an ocular lens power of 10 x?
10 x * 40x = 400x
If a microscope lens has a magnification of 15 and another has a magnification of 40 what is the total magnification of the microscope?
it would be 15 times 40 which is 600 times magnification
What is the objective lens on a microscope?
An optical microscope used in a laboratory would have 3 different types of lenses.They are :-(1) Condenser lens- directs light to the specimen if there is no in built light source.(2) Eye piece - lens close to the eye of the observer which magnifies the image created by the objective lens.(3) Objective - These are the lenses which are positioned closest to the specimen mounted on the stage of the microscope which magnifies the specimen. There could be several objective lenses in an optical microscope, generally three. The low power objective (usually magnifies 4 times), mid power objective (usually magnifies 10 times) and the high power objective (usually magnifies 40 times).
What is the effect of changing from lower power objectives to higher power objectives?
Low power objective magnifies the object by 10 times, whereas high power objective magnifies 40 times. When we change from low power to high power, the object appears larger, exactly 4 times larger than low power. Low power objective covers a larger area, whereas high power covers a smaller area.
What Equals eyepiece times objective lens?
Example: 4 = Low Power 10 = Med. Power 40 = High Power 100 = Eyepiece Low Power x Eyepiece = 40x Med. Power x Eyepiece = 100x High Power x Eyepiece = 400x
How is macroscopic magnification computed?
The eye piece provides x10 magnification, and times it by the low power objective. (Smallest tube) So, if the low power objective was x10, and the eye piece being 10, then the magnification would be x100 Use this for other objectives too.
What does 40 equal to?
It equals 40. If you are prepared for it, it also equals 39.999... (repeating).
Which focus should you use first when using a microscope to view a slide?
10x4=40 power its the farthest and shall give you farther view if you would like you can move closer to 10x10= 100 power or the highest 10x40 400 power
What does 40 40 equal?
