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.

How thickness effects on focal length of convex?
As the thickness of a convex lens increases, the focal length decreases. This is because a thicker lens has a more curved surface, which causes light to converge more quickly. The focal length is the distance at which the light converges, so a thicker lens leads to a shorter focal length.
How does the thickness of a convex lens affect a focal length?
A thicker convex lens has a shorter focal length. This is because the curvature of the lens is more pronounced, causing light rays to converge more quickly to a point. Conversely, a thinner lens has a longer focal length due to its flatter curvature, causing light rays to converge more gradually.
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.
Do convex lenses have negative focal length?
No, convex lenses have positive focal lengths. The focal length is the distance from the lens to its focal point where light rays converge. In convex lenses, parallel light rays are focused to a point on the opposite side of the lens, resulting in a positive focal length.
Do thick convex lenses have longer or shorter focal lengths than thin convex lenses?
As a thicker lens has more material to do bend the light further it it would have a shorter focal length
What is the difference between a thick convex lens and a thin convex lens?
A thick convex lens has a larger thickness and can bend light rays more than a thin convex lens. This results in a shorter focal length and stronger focusing ability for a thick convex lens compared to a thin convex lens.
What is the focal length of the convex lens?
The distance from the centre of the lens to the focal point.
Why focal length of convex lens is easier to find than a concave lense?
The focal length of a convex lens is easier to find than a concave lens because for a convex lens, the focal length is positive and is measured from the lens to the focal point. In contrast, for a concave lens, the focal length is negative and the rays of light are diverged. This makes it more challenging to find the focal point accurately.
What is the power of a convex lens with 10cm focal length?
The power of a lens is calculated as the reciprocal of its focal length in meters. Therefore, a convex lens with a 10 cm focal length has a power of +10 diopters.
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 happens to the focal length of convex lens when convex lens is cutted vertically along the optic center?
its focal lenght becomes 2f
How does change in the thickness of lens change the focal length of lens?
Increasing the thickness of the lens generally decreases the focal length, while decreasing the thickness increases the focal length. This is due to the way light rays bend and converge or diverge as they pass through different thicknesses of the lens. The relationship between lens thickness and focal length is determined by the lens's refractive index and curvature.
