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.
What else can I help you with?
This telescope uses mirrors to gather and focus light energy?
Newtonian telescope
What is the name of the telescope that uses convex lenses to gather and focus light?
Refracting telescope.
What is meant by the size of a telescope?
The size of a telescope almost invariably refers to the size of it's objective lens, or mirror. It translates to how much light the telescope can gather, not "how big it can magnify", which is very secondary.
Which type of telescope did Galileo turn skyward in 1610?
Galileo turned a refracting telescope, which uses lenses to gather and focus light, skyward in 1610. This allowed him to make groundbreaking astronomical observations such as the moons of Jupiter and the phases of Venus.
What type of telescope is the Subaru telescope?
