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.
Lenses have different focal lengths due to their varying shapes and materials. A thicker lens will have a shorter focal length, while a thinner lens will have a longer focal length. Additionally, the refractive index of the lens material will affect its focal length.
Power in optics is inversely proportional to the focal length of a lens. A lens with a shorter focal length will have greater optical power, while a lens with a longer focal length will have less optical power. This relationship is important in determining the strength and magnification of corrective lenses used in eyeglasses and contact lenses.
The focal length of a telephoto lens is longer than the focal length of a wide-angle lens. Telephoto lenses have a narrow field of view and are ideal for capturing distant subjects, while wide-angle lenses have a wider field of view and are great for capturing expansive scenes.
Curvature and focal length are inversely related. A shorter focal length corresponds to more curved surfaces, while a longer focal length results in flatter surfaces. This relationship is seen in various optical systems like lenses and mirrors.

because thick lenses have small focal length . this causes chromatic aberration. hence it can be minimised by increacing the focal length of lens or by using thin lenses which have high focal length.
Power (F)= 1/focal length (f) focal length f, is measured in meters the power, F, is in dioptres (D) In converging or convex lenses the power is positive In diverging or concave lenses, the power is negative :)

There are many types of lenses used in photography and optics. Some common types include: Prime lenses: Have a fixed focal length and do not zoom. Zoom lenses: Can change focal length to provide different magnifications. Wide-angle lenses: Have a short focal length, capturing a wider field of view. Telephoto lenses: Have a longer focal length, allowing for capturing distant subjects.
The Center of curvature is 2 times the focal length. By the way this is a physics question.

Thick concave lenses have shorter focal lengths than thin concave lenses. This is due to the increased curvature of the lens surfaces in thick lenses, which causes light rays to converge more quickly to a focal point.
Convex lenses have shorter focal lengths than thin convex lenses because they are thicker and have a higher refractive index, which causes light rays to converge more quickly. This results in a shorter focal length and a more powerful focusing ability.
The curvature of the lens surfaces and the refractive index of the material the lens is made of determine the focal length of a lens. Thicker lenses with more curved surfaces have shorter focal lengths, while thinner lenses with less curved surfaces have longer focal lengths.
