sag hight of lense 1.53 ? radius of lense index 1.498
I can use it when lines are joined together
prove any two adjacent triangles as congruent
In geometry, deductive rules can be used to prove conjectures.
To prove by contradiction, you assume that an opposite assumption is true, then disprove the opposite statement.
prove that QR = QR by the reflexive property.
See the link below for the formula of lens power.
The formula for the area of a rectangle is length x breadth. In order to prove this works, work out an area of a rectangle using that formula.
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!
I believe it can be used for any lens. Just be sure to use the correct sign. Check the "lensmaker's equation" in Wikipedia, and the comments about what sign to use.
Prove it by induction on n, use 0 or 1 as base cases.
The formula which is used to find out the amount of induced prism in a lens is the Prentice rule. Decentration is multiplied by lens power to get the amount of prism correction.
The formula for calculating a lens' refractive power is as follows:n = (D * R) + 1, where n = refractive power, D = optical power in diopter, and R = lens curvature radius.A lens clock will give you an estimated optical power, d and from there you can work out the curvature radius by using the formula:R = (0.53)/d.A lensometer will give you the actual optical power, D.Input the R and D into the first formula and you will get the lens' refractive index, n.
You would have a difficult time finding a formula to prove that statement, for two main reasons: 1). The statement is false. A triangle is never a rhombus. 2). Formulas can describe things, but they can't 'prove' things.
A "lens" is "glass". However, lens glass is quite different from a drinking glass. making a lens u must consider: magnifying power clarity color transmission These features involve: getting the geometry right minimizing imperfections making the right formula with the proper additives
94 to be exact
The formula for the resolution of an objective lens isR = (1.22(lamda))/(2*(NA))Where (lamda) is wavelength and (NA) is the numerical aperture
This is an approximate formula. For a biconvex lens, the two radii of curvature are measured in opposite directions and you therefore have opposite signs for u and v.
