What is the lens maker formula and how is it used to calculate the focal length of a lens?
The lens maker formula is a mathematical equation used to calculate the focal length of a lens based on its refractive index and the radii of curvature of its surfaces. It is expressed as:
1/f (n - 1) (1/R1 - 1/R2)
Where:
- f is the focal length of the lens
- n is the refractive index of the lens material
- R1 is the radius of curvature of the first lens surface
- R2 is the radius of curvature of the second lens surface
By plugging in the values for n, R1, and R2 into the formula, you can calculate the focal length of the lens. This formula is essential for lens designers and manufacturers to ensure that lenses have the desired optical properties for various applications.

How do you calculate focal length of lens?
The focal length of a lens can be calculated by measuring the distance between the lens and the image plane when an object far away is in focus. This distance is the focal length of the lens. Alternatively, the focal length can be found using the lens maker's formula: 1/f = (n-1) * (1/R1 - 1/R2), where f is the focal length, n is the refractive index of the lens material, and R1 and R2 are the radii of curvature of the two lens surfaces.
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!
Relation between focal length and refractive index?
the wave's speed v is related to both the frequency f and the wavelength l :v = l f.Combining the above expression for velocity with the definition of index of refraction, we find a relationship between the wavelength l = v/f in a medium and the wavelength l 0 = c/f in vacuum:In the above equation, the frequencies cancel because frequency does not change as light moves from one medium to another.
What is the difference between the two types of lenses?
I assume that the the question deals with concave and convex lenses. Light rays entering a flat surface and exiting a convex side of a lens will be spread apart enlarging the image. Light entering a flat surface and exiting the concave part of the lens will make the image smaller at close distances, then invert the object at greater distances. There are combinations of lenses that make the image more complex to describe. Now I must add it does matter what distance the image on a screen is from the source as to how the source appears. To know this you need to know the focal length of the lens. If f is the focal length the lens maker uses, and o is the object projecting light's distance from the lens and i is the distance we observe the object after it passes through the lens, the 1/o+1/i =1/f.

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.

Will focal length of a plane mirror change when placed in water?
Nope.. because mirror doesn't forms images by following laws of refraction they follows laws of reflection. consider a plane immersed in the liquid, obviously beam of light will bend(refraction of the liquid) but when it reaches the surface it simply reflects back(laws of reflection) thus the condition will be again satisfied Angle i=Angle r. only in case of lens it changes(By lens maker's formula)
What is the length of the barrel on a colt peace maker revolver?

How do you calculate the length of injection molding zones?
Runners and Gates are determined by the design of the part being molded and the size of the injection molded machine and is best left to molder's tool maker to determine and usually fine tune during the first run of parts

How to calculate a scaled score for a standardized test?
To calculate a scaled score for a standardized test, you first need to determine the raw score (the number of correct answers). Then, you use a conversion table or formula provided by the test maker to convert the raw score into a scaled score. The scaled score is adjusted to account for the difficulty of the test and allows for fair comparisons between test takers.
