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.

Why the study was under taken of focal length of a convex lens by graphical method?
to determine the focal length of a convex mirror.
Which lens has a greater power convex lens of focal length 10 cm or a convex lens of focal length 20cm?
Power is inversely related to the focal length. So convex lens of focal length 20 cm has less power compared to that having focal length 10 cm
What is the focal length of the convex lens?
The distance from the centre of the lens to the focal point.
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 :)
What happens to the focal length of convex lens when convex lens is cutted vertically along the optic center?
its focal lenght becomes 2f
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.
Why a small focal length convex lens is used in simple microscope?
because manifying power has inerse relation with that of focal length
The relation between focal length and radius of curvature of spherical mirror is?
The focal length of a convex mirror is half of its radius of curvature.
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.
How does the thickness of a lens affect the focal length of a lens?
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 is the power of a convex lens with 10cm focal length?
1.0 diopters
What happens to focal length when convex lens is cut horizontally?
no change
