How does a focal length change as a convex lens becomes flatter?
As a convex lens becomes flatter, its focal length increases. This is because a flatter lens causes light to converge less, resulting in a longer focal length. Conversely, a more curved lens brings light to a focus more quickly.
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.
Does the focal length of a convex lens get smaller when they become more curved?
Yes, as a convex lens becomes more curved, its focal length decreases. This is because a more curved lens causes light rays to converge at a point closer to the lens, resulting in a shorter focal length.
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.
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.

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!
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 the thickness of a convex lens affect a focal length?

Yes, as a convex lens becomes more curved, its focal length decreases. This is because a more curved lens causes light rays to converge at a point closer to the lens, resulting in a shorter 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.
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.

Will focal length of a concave mirror would increase decrease stay the same if the mirror were made flatter?
If a concave mirror is made flatter, its focal length will increase. This is because a flatter mirror has a larger radius of curvature, resulting in light rays converging at a point farther away from the mirror.
Length of the spring is halved then the spring constant becomes?
If the length of the spring is halved, the spring constant remains the same. The spring constant is determined by the material and shape of the spring, and is not affected by changes in length.
What happens to focal length when convex lens is cut horizontally?
no change
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.
