How much more light gathering power does a 5 meter diameter telescope have as compared to the human eye?
The primary mirrors of each of the two telescopes are 10 meters (33 ft) in diameter. A human eye has a pupil less than 8mm in diameter. The area of a Keck mirror is about 1,6 million times larger than that of the human pupil. (The sensors used are more sensitive too able to detect single photons).
What else can I help you with?
How much more light can a telescope with an objective that is 31 inches in diameter gather when compared to a telescope that is 19 inches in diameter Enter the number with on units?
A nineteen inch objective gathers a bit over 4,000 times as much light as the unaided human eye. A 31 inch objective gathers about 10,670 times as much light as the human eye, or a little more than two-and-a-half times the nineteen inch objective. ======================> 2.662 times
Telescope lenses are able to gather more light than the lens of the human eye primarily because telescope lenses are?
Larger in diameter. The human eye can open to a maximum of about 7mm. Calculate the area of that, and compare it with a 50 diamter mm lens. (A=pi*r^2). Where 3.5 = radius of the pupil and: 25 = radius of the lens pi * 3.5^2 mm = 21.99 mm ^2 (area of a pupil in the dark) pi* 25^2mm = 1963.5 mm^2 Therefore, a 50 mm lens would have 89.29 more light grasp than the eye.
How does a telescope help astronomers see more stars?
A telescope has a larger gathering area (the main lens, or the main mirror) than the human eye. This makes it possible to see the light of fainter objects. Another thing the telescope does is to increase angular resolution. This makes it possible, in some cases, to see two stars that are close together as two stars, whereas the human eye would see them as a single spot of light.

Size of a virus compared to a human cell?
A virus is much smaller than a human cell, typically ranging in size from 20 to 400 nanometers, while a human cell can range from 10 to 30 micrometers in size. This size difference is due to the simpler structure of a virus, which consists of genetic material surrounded by a protein coat, compared to the complex organelles and structures found within a human cell.

How does the telescope make it possible to see distant objets?
A telescope works like a huge eye. The human eye, in the dark, is only about 7mm in diameter fully dilated. An easily-affordable 6-inch reflecting telescope is 152.4mm in diameter. This works for refractors, too, but they are much more expensive per inch of diameter. Therefore, the telescope is 21.7 times larger in diameter. But, there is more to it than this! The area of the eye is 76.2 square mm. The area of a 6 inch telescope is 2026.83 square mm. From, area of a circle = pi*r^2, (Note -- Radius, not diameter!) knowing that 1 inch = 25.4 mm, From this, 18241.51/38.48 equals 474.05, making the telescope have 474.05 times more light grasp than the human eye. Each magnitude of star is 2.5 times that of the one above or below it, progressively. Therefore, we can see far dimmer stars with the telescope than with the unaided eye, between 7 and 8 times dimmer on the magnitude scale.
How do the diameter and concentration of bovine red blood cells compare to human red blood cells?
Bovine red blood cells are slightly larger with a diameter of about 6-8 μm compared to human red blood cells, which have a diameter of about 6-7 μm. The concentration of red blood cells in bovine blood is lower than in human blood, with a hematocrit of around 30-35% for cows compared to 40-50% for humans.

What is the one millionth of a meter of a human hair?
One millionth of a meter is referred to as a micrometer (or micron). Human hair typically has a diameter ranging from about 17 to 180 micrometers, depending on the individual and hair type. Thus, a micrometer is significantly smaller than the diameter of a human hair, illustrating just how fine human hair can be compared to other measurements.
What is smaller a tip of human hair or a transistors?
A tip of a human hair is typically larger than a transistor. Transistors, being microscopic devices used in electronic circuits, are much smaller in size compared to the diameter of a human hair.
What are the advantages of using a telescope compared to making observations with unaided eye?
Telescopes can make it easy to see all the way into space, where as the human eye can not see very far at all.
