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 lens affect the focal length of a lens?
There are three factors affecting the focal length of a lens. 1. refractive index of the material of lens. 2. refractive index of the surrounding medium 3. the radius of curvature of the lens surfaces.
What will happen to the focal length of a lens if it is cut into half vertically?
When the lens is cut vertically then the focal length of the lens will increase.the focal length will become approx double.
How focal length of a lens change when apparatus immersed in water?
The focal length of a lens decreases when it is immersed in water due to the change in the refractive index of the medium. This change causes the light rays passing through the lens to bend differently, altering the focal point of the lens.
What is the lens focal length formula used to calculate the focal length of a camera lens?
The lens focal length formula used to calculate the focal length of a camera lens is: Focal Length (Distance between lens and image sensor) / (1 (Distance between lens and object) / (Distance between lens and object))

How does thickness of convex lens affect focal length?
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 focal length of a lens change when apparatus immersed in water?
The focal length of a lens decreases when it is immersed in water due to the change in the refractive index of the medium. This change causes the light rays passing through the lens to bend differently, altering the focal point of the lens.
How does a lens adapter affect the focal length of a camera lens?
A lens adapter can change the focal length of a camera lens by either increasing or decreasing it, depending on the specific adapter used.
What is the lens focal length formula used to calculate the focal length of a camera lens?
The lens focal length formula used to calculate the focal length of a camera lens is: Focal Length (Distance between lens and image sensor) / (1 (Distance between lens and object) / (Distance between lens and object))
Length of a lens is the distance from the center of the lens to its principal focus?
It is called the focal length. It is equal to 1/2 times r, and is positive on concave mirrors and negative on convex mirrors.
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.
What factors can affect the focal length of a lens?
There are many factors affecting the focal length of a lens, these include: - The thickness of a lens. - The curviture of a lens. - The material the lens is made out of. E.g. Glass or plastic. - The light intensity going through the lens. - The shape of the lens. These, are just few of the many factors that may affect the focal length of a particular lens. I hope this has helped.
What is the difference between a zoom lens and a telephoto lens?
A zoom lens can change its focal length, allowing you to zoom in and out on a subject. A telephoto lens has a fixed focal length and provides a magnified view of distant subjects.
Does a diverging lens have a focal length?
Yes, a diverging lens does have a focal length. The focal length of a diverging lens is negative, as the light rays diverge after passing through the lens.
