The focal point F and focal length f of a positive (convex) lens, a negative (concave) lens, a concave mirror, and a convex mirror. The focal length of an optical system is a measure of how strongly the system converges or diverges light.

What are the negative factors of a positive number?
The same as the positive ones with negative signs.
You opened your PS2 to clean the lens and it won't power on What can you do?
This isn't positive..but try re-plug it into the wall...If that doesn't work, You might have to buy a new one...
What are all the multiples of negative numbers?
The same way as finding factors of positive numbers but the answer includes both the positive and negative factors.
How can we find the LCM of negative numbers?
The same as with positive numbers. You need at least two numbers to find a GCF.
What is the GCD of two negative numbers?
Since negative numbers also have positive factors, their GCF would be the same as if the original numbers were positive.
What is a positive lens the same as?
A positive lens is also called a magnifying lens. It has convex surfaces and it has a measureable focal length where it produces an inverted image of a distant object. The power in dioptres is the reciprocal of the focal length in metres.
What objective lens is the longest?
The lens with the greatest (positive) curvature. The lens with the highest diopter.
Is convex lens have a positive or negative magnification?
Positive.Positive.Positive.Positive.
Does positive meniscus lens correct myopia?
Nope, a negative meniscus lens corrects myopia. Positive meniscus corrects hyperopia.
Is optical center is same as the geometric center of a lens?
no it is same
What is a negative lens is the same as?
If the lens equation yields a negative image distance, then the image is a virtual image on the same side of the lens as the object. If it yields a negative focal length, then the lens is a diverging lens rather than the converging lens in the illustration.
A convex lens is also called a lens?
converging lens
If the image produced by a lens is the same size as the object then the lens must be?
convex lens at 2c
What happens when you put a wide angle lens on a camera with a fisheye lens at the same time?
A fisheye lens IS a wide angle lens
Is lens the same as mirror?
a lens you can see through and a mirror reflects
Why zone plate act like a convergent lens?
Zone plate acts like a converging lens because n, which refers to order or any integer can take a positive value. When n takes a positive value, the zone plate acts just like a converging lens.
What is the difference between lense and lens?
"Lense" is a misspelling of "lens," which is the correct spelling referring to a curved piece of glass or other transparent material that focuses or disperses light rays.
