What is the focal length of sunglasses?
The focal length of a Sunglass lens is theoretically infinite. It is because the radii of curvatures of the front and back surfaces are equal.
What factor determines the focal length of a lens?
It is determined by the radii of curvature of its two faces.
What determines the focal length of two sides of a lens?
Their radii of curvature and the refractive index of the material of the lens.
What is the focal point in a composition in art called?
In art a composition's focal point is actually called the focal point. There may be multiple focal points, in which case the main one is the focal point and the others are secondary focal points. You can recognize the focal point because it is somehow set apart from the rest of the composition.
Difference between focal point and focal length?
The focal point is the point where light converges after it passes through a concave lens. The focal length is the distance of the focal point to the lens. Same for a convex lens, except that the focal point is the imaginary point from where light deflected from lens seems to have emerged.

How does thickness of convex lens affect focal length?
The focal length of a lens depends on 1. The refractive index of the material 2. Radii of the curvature of the two faces. The lens maker's formula is 1/f = (mu --1) (1/R1 --1/R2) mu- the refractive index of the material with which lens is made R1 and R2 are the radii of curvature of the faces. f- the focal length of the lens thus formed. your question needs clear information. As the thickness of the lens of same diameter is increased then radii of curvature would decrease, hence focal length would decrease. But as the diameter gets increased then there comes a chance of maintaining the radii of curvature to be the same. If so, then no change in the focal length. But, if diameter is not increased to the right extent then we cannot be sure about the variation of focal length.
What determines the focal length of two sides of a lens?
Their radii of curvature and the refractive index of the material of the lens.
What is the difference between atomic radii and ionic radii?
atomci radii measures for an atom ionic radii measures for an ion
How many radii a sphere have?
There are infinite radii in a sphere.
What are radii shoes?
Radii is a brand of sports footwear.
What is the sum of radii?
2 radii = one diameter
What is the covalent radii of hydrogen sulfide?
The covalent radii is for atoms.
What element has the smallest radii?
A hydrogen atom has the smallest radii.
What is a sentence using radii?
These three radii are of different lengths.
Singular form of radii?
the single form of radii is radius
