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
Why is 40 degress celsius hot?
Because 40 degrees Celsius is equal to a temperature of 104 degrees Fahrenheit.
What is 40 degrees Celsius in Fahrenheit degrees?
40 degrees Celsius is equal to a temperature of 104 degrees Fahrenheit.
What is the power of the microscope?
The power of a light microscope can be determined by multiplying the magnification power of the eyepiece by the magnification power of the current lens. Ex. (10x) by (40x) results in in a 400x magnification.
What is 40 to the tenth power?
40^10 is equal to 10,485,760,000,000,000.
How many times will a microscope lens with a power of 40X magnify an object?
A microscope lens with a power of 40X will magnify an object 40 times its actual size.
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
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 5 to the power of 40?
5 to the power of 40 is equal to 9,094,947,017,729,280,000. This can be calculated by multiplying 5 by itself 40 times. In mathematical notation, it is written as 5^40. This number is extremely large and is often expressed in scientific notation for easier understanding.
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 is 2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2?
The expression 2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2 can be simplified by multiplying all the 2s together. This results in 2 raised to the power of 20, which is equal to 1,048,576.
What is 400 times 10 to the 3rd power?
400 x 10^3 is equal to 400,000.
