How do focal length changes as a convex lens becomes flatter?
As a convex lens becomes flatter, its focal length increases. This is because a flatter lens bends light rays less, causing them to converge further away before focusing, resulting in a longer 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.
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.
How do focal length changes as a convex lens becomes flatter?
As a convex lens becomes flatter, its focal length increases. This is because a flatter lens bends light rays less, causing them to converge further away before focusing, resulting in a longer 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!
What happens to the focal length of convex lens when convex lens is cutted vertically along the optic center?
its focal lenght becomes 2f
What happens to focal length when convex lens is cut horizontally?
no change

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.

If a convex lens of focal length f splits into two equal parts what will be the new focal length?
there can be two ways to cut a convex lens into two equal parts-- one, along the principal axis and another, perpendicular to the principal axis. If the lens is cut along the principal axis, then there will bo NO change in the focal length of the lens. But, if it is cut perpendicular to the principal axis, then the focal length will be twice the original one.
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.
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 :)
