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.

Does light travel easier through a convex lens or a concave lens?
The "ease" with which light travels through a lens has to do with the material the lens is made of. If a concave and convex lens are both made of the same material, say, silicon glass, then the light behaves in an identical way within both lenses. What happens on the front and back sides of the surface of the lens is a different story. This is because the light will be reflected and refracted differently by the different lenses because of their shape. But the light behaves the same way within both lenses as it is passing through.
What are the three laws governing light passing through a converging lens?
Any incident ray traveling parallel to the principal axis of a converging lens will refract through the lens and travel through the focal point on the opposite side of the lens.Any incident ray traveling through the focal point on the way to the lens will refract through the lens and travel parallel to the principal axis.An incident ray that passes through the center of the lens will in effect continue in the same direction that it had when it entered the lens.
Are positive wire and hot wires the same?
yes
You got 10mm lens and 20mm lens for your telescope What is the difference?
10mm lens is more powerful than the 20mm lens
What is the significance of the term compound in describing a modern light microscope?
A compound microscope contains an objective lens with a very short focal length and an eyepiece with a longer focal length. Both lens are mounted in the same tube.
What is the positive lens is the same as?
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 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 kind of oakleys do jose bautista have?
they are flak jackets with positive red iridium lens.
