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.

Why is concave lens called a negative lens?
Concave lens is called a negative lens because it has a negative focal length.
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 does a single negative lens produce?
A divergent beam.
Is optical center is same as the geometric center of a lens?
no it is same
Is convex lens have a positive or negative magnification?
Positive.Positive.Positive.Positive.
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
Does positive meniscus lens correct myopia?
Nope, a negative meniscus lens corrects myopia. Positive meniscus corrects hyperopia.
What kind of images does a single negative lens produce?
It produces only a virtual image in front of the lens.
Is lens the same as mirror?
a lens you can see through and a mirror reflects
What part of the eye name the same?
Lens
