What else can I help you with?
Is the image larger or smaller through a convex lens?
both according to the position of the image in front of the lensif placed in infiniity or beyond the centre of curvature the image will be small if placed between centre of curvatureand pole the image will be bigger in size
What is Another name of convex and concave lens?
A convex lens is also known as a converging lens, while a concave lens is also known as a diverging lens.
What does a 58mm lens mean?
A 58mm lens refers to the diameter of the lens barrel at the front of the lens. This measurement is important for selecting compatible lens filters and accessories. It does not directly relate to the focal length or zoom capability of the lens.
Is a convex lens a minus or plus lens?
Convex lens are plus lenses, while concave lens are minus lenseses.
Is a lens that is thicker at the edges than in the middle a concave lens?
Yes, this is a concave lens. It is also called a diverging lens because it causes light rays to spread out.
What is the easiest net for a sphere?
The net consists of a series of vertical lenticular (lens-shaped) sections that are joined together at their middle.The lenticular sections are flattened slices of the surface of the sphere from "north pole" to "south pole", taking in a few longitudes each, joined together along the "equator".See link for an illustration.The net consists of a series of vertical lenticular (lens-shaped) sections that are joined together at their middle.The lenticular sections are flattened slices of the surface of the sphere from "north pole" to "south pole", taking in a few longitudes each, joined together along the "equator".See link for an illustration.The net consists of a series of vertical lenticular (lens-shaped) sections that are joined together at their middle.The lenticular sections are flattened slices of the surface of the sphere from "north pole" to "south pole", taking in a few longitudes each, joined together along the "equator".See link for an illustration.The net consists of a series of vertical lenticular (lens-shaped) sections that are joined together at their middle.The lenticular sections are flattened slices of the surface of the sphere from "north pole" to "south pole", taking in a few longitudes each, joined together along the "equator".See link for an illustration.

What is the derivation of lens maker?
Derivation of Lens-maker's Formula:Derivation of Lens-Maker's formula: As shown in figure the centre of the lens is denoted as C and the principal axis is X'X. The R1 and R2 are the radii of the curvature of the surfaces of lens and the poles are P1 and P2. The variable t represents the thickness of the lens which has the small value. The object in principal axis is O. The distance between the point object and the pole P1 is u. The image of point object O is refracted at I which has the distance v' from the pole P1.Based on the refraction formula of the spherical surface,- =In second surface the virtual object is denoted as I' after completion of refraction the final complete image should be created at I. The distance between the final object I and the pole is v. The distance between the virtual object I' and the pole P2 is (v'-t).If there is refraction at second medium then the ray is moving from the second medium to first medium.Derivation of Lens-maker's Formula:Refraction formula, - = -----------------------------(1)Here the value of t is negligible because it has very small value. Therefore the equation becomes- = - --------------------------------(2)By adding the equations (1) and (2) we get,- ===Where the refractive index of the second medium is denoted as which is related to the first medium.When the object is at infinity, the image should be created at second focus. That is u=∞, v=f2=f.=Therefore refraction formula for thin lens:=Which is known as Lens-Maker's formula.Consider the air is the first medium and n be the refractive index of the material. In thisNow the derivation of Lens-Maker's formula is,= (n-1)

Is it fish pole or fishing pole?
It is a pole for fishing, a fishing pole. To be a fish pole, the pole would have to be made out of fish or it would have to be a pole that a fish uses.
