There are three factors affecting the focal length of a lens.
1. refractive index of the material of lens.
2. refractive index of the surrounding medium
3. the radius of curvature of the lens surfaces.

What factors can affect the focal length of a lens?
There are many factors affecting the focal length of a lens, these include: - The thickness of a lens. - The curviture of a lens. - The material the lens is made out of. E.g. Glass or plastic. - The light intensity going through the lens. - The shape of the lens. These, are just few of the many factors that may affect the focal length of a particular lens. I hope this has helped.
How does change in the thickness of lens change the focal length of lens?
Not at all. The focal length is determined by the curvature of the surfaces.
Whats the focal length of a lens?
The focal length of a lens is the distance from the principal foci to the center of the lens.
Factors affecting for length of a convex lens by the lens displacement method using cojugate foci?
There are many factors that can affect the focal length of a convex lens. These include: - The thickness of the lens - The type of material that the lens is made ot of - The curviture of the lens - How big the distance between the lens and the image you are viewing is. This is obviously a major factor due to the fact the the focal length is where all the light becomes concentrated and the image becomes clear as pristine. I hope this has helped those seeking the answer to the question above. I know this information as I am doing a controlled assessment all about 'How Factors Affect The Focal Lenght/ Point Of A Convex Lens'. Thankyou for viewing. Samia :)
Length of a lens is the distance from the center of the lens to its principal focus?
It is called the focal length. It is equal to 1/2 times r, and is positive on concave mirrors and negative on convex mirrors.

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.

Explain how the focal length changes as a convex lens becomes flatter?
The focal length of a lens is the distance from the center of the lens to the point at which it focuses light rays. The bigger the focal length, the more powerful the lens. ChaCha!
How does the eyepiece affect the total magnifacation in a telescope?
A telescope consists of two lenses. 1) The main lens which collects the light ( it is relatively bigger that eyepiece). 2) Eye piece , through which we see. Magnification of a telescope depends on the focal length of the eye piece and the main lens. Magnification = Focal length of the main lens / Focal length of the eyepiece . For example : If the focal length of the main lens is 12 units and the focal length of the eyepiece is 2 units , then the magnification will be 12/2 = 6.When the focal length of the main lens is constant , the focal length of the eyepiece is inversely proportional to the magnification.
Why do the focal length decrease as the thickness of the lens increase?
The angle of refraction increases, though it's a function of curvature rather than actual thickness.

Does the focal lens length have three classifications?
yes, focal lens length has three classifications
What is defined as the distance between a lens and its focal point?
focal length of the lens
What is the focal length of the convex lens?
The distance from the centre of the lens to the focal point.
