Which lens have zero power?
A flat piece of glass. Also, any lens where the shape of the convex part matches the shape of the concave part. An example would be a flat piece of glass bent over a sphere.
What is the meaning of irregularities?
of Irregularity
What is the plural for irregularity?
irregularities
What shape has exactly one pair of adjecent sides?
Any polygon must have at least three sides. So a shape with only one pair of adjacent sides must be lenticular (shaped like a lens) else it is some very odd shape.
What shape has 0 vertices 2 edges 2 faces?
I do not think there is any shape that you would come across normally. One shape that I can think of is a bi-convex lens with a partial ridge. I am not entirely sure that the ridge counts as an edge, but that's my best offer.
What shape is a lens?
a shape of a lens is curved outwards and concave one are curved in wards
What lens is a converging lens double-convex spherical-convex plano-concave or convexo-concave lens?
A converging lens is also known as a magnifying lens. The shape of the lens is a double convex shape.
What is the shape of a testicle?
The testes should be free from lumps, pain, irregularities and swelling.
What role does the lens play?
The role of a lens is to converge and or diverge light depending on the shape of the lens.
What shape has 2 faces1 edge and no vertex?
A lenticular shape: the shape of a lens.
How the lens change it shape when foucsing on near objects?
The lens changes its shape by becoming more convex (thicker in the middle) when focusing on near objects. This shape change is controlled by ciliary muscles in the eye that pull on the lens to make it rounder, allowing for proper focusing on close-up objects.
Does the shape of the lens change when you sqeeze it?
NO
What shape is the lens?
A concave circle
What shape is the lens in a camera?
Rectangle
Which lens is a converging lens a double-convex lens or a spherical-convex lens or a plano-concave lens or a convexo-concave lens?
Your are mixing properties. Converging lens is always thicker in the centre and thinner at the edges. The other cathegory is the geometry of shape of the surfaces of the lens. Convex means that the shape is similar to the outer surbace of a sphere, concave means that the shape is similar to the iner surface of a sphere (or: convex = lower side of a spoon as we use it for sampling a soup; concave: upper (inner) shape of the spoon). A double convex lens is always a converging lens. A plano-concave lens is always a diverging (not converging) lens. A convexo-concave lens is the most usual shape of a lense used in spectacles. It can be either converging or diverging, depending on the radii of the surfaces.
What appearance does the eye's lens have?
The lens is normally transparent, elliptical in shape, and somewhat elastic.
What shape are the lens inside your eyes?
convex
