A careful reading of the question raises the uncomfortable suspicion that it might be
very difficult to put the focal length in water.
However, it's quite possible to put the lens itself in water. When that's done, it's quite
likely that the lens's focal length has changed. The refractive indexes of both materials ...
the substance of which the lens is made and the medium around it ... are both involved in
determining its focal length.
What else can I help you with?
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.
Does the focal length of a spherical mirror or lens change when placed under water?
i do not think so because a mirror an a lens is two same things except that mirrors can reflect the water and the lens may refract or bend the water so that can change the focal length between the mirror and the lens
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 does change in the thickness of lens change the focal length of lens?
Increasing the thickness of the lens generally decreases the focal length, while decreasing the thickness increases the focal length. This is due to the way light rays bend and converge or diverge as they pass through different thicknesses of the lens. The relationship between lens thickness and focal length is determined by the lens's refractive index and curvature.
Will the focal length of concave lens change in water?
no, because this happens only in the cases of lenses
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.
A concave mirror and a convex lens are held in waterwhat changes if any do you expect in their focal length?
Excellent question. The answer is actually yes! According to the lens makers formula, it will change based on the refractive index of the material of the concave mirror wrt the medium. Google Lens makers formula for better understanding! NO! the focal length of the mirror will not change if it would be a lens then the focal length would change. The lens maker's formula is for Lenses only!
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 do you find the new focal length when the lence is put in to the water?
to find the new focal length when the lens is put into water it becomes the 4 times the focal length in air.
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.
