d focal lenght increases due to increases in the distance between centre of curvature and the centre of the convex lens on the principal axis

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 will happen to the focal length of a concave mirror or a convex mirror when the incident violet light on them is replaced by red light?
Nothing. The focal length is defined as point where all of the light converges after passing through the lens ( for a convex mirror)and only depends on the mirror's curvature. So changing the incident light ray will cause no change in the focal length of the 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
When do convex lens produce real image?
When the object length is less than the focal length
What is the power of a convex lens with 10cm focal length?
1.0 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
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.

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.

1.0 diopters
What is the length of a diagonal in parallelogram when both the sides are given?
It cannot be determined. Think of a square and distort it as a rhombus. As the rhombus gets flatter, one of the diagonals becomes smaller and the other becomes larger. The same applies to a parallelogram. You can only determine the maximum or minimum length of the diagonals. The maximum is the sum of the two sides, the minimum is zero. Neither extreme is attainable but you can get as close to them as you like.
What is the focal length of the convex lens?
The distance from the centre of the lens to the focal point.
