  2. Fresnel equations - Wikipedia

    en.wikipedia.org/wiki/Fresnel_equations

    That means that there is an equal amount of power in the s and p polarizations, so that the effective reflectivity of the material is just the average of the two reflectivities: = (+). For low-precision applications involving unpolarized light, such as computer graphics , rather than rigorously computing the effective reflection coefficient for ...

  4. Absorbance - Wikipedia

    en.wikipedia.org/wiki/Absorbance

    Absorbance is defined as "the logarithm of the ratio of incident to transmitted radiant power through a sample (excluding the effects on cell walls)". [1] Alternatively, for samples which scatter light, absorbance may be defined as "the negative logarithm of one minus absorptance, as measured on a uniform sample". [2]

    However the titles of bonds issued by governments and other issuers use the fractional form, e.g. "3 + 1 ⁄ 2 % Unsecured Loan Stock 2032 Series 2". (When interest rates are very low, the number 0 is included if the interest rate is less than 1%, e.g. "0 + 3 ⁄ 4 % Treasury Stock", not "3 ⁄ 4 % Treasury Stock".) It is also widely accepted ...

    An infinite series of any rational function of can be reduced to a finite series of polygamma functions, by use of partial fraction decomposition, [8] as explained here. This fact can also be applied to finite series of rational functions, allowing the result to be computed in constant time even when the series contains a large number of terms.

    In the second step, they were divided by 3. The final result, ⁠ 4 / 3 ⁠, is an irreducible fraction because 4 and 3 have no common factors other than 1. The original fraction could have also been reduced in a single step by using the greatest common divisor of 90 and 120, which is 30. As 120 ÷ 30 = 4, and 90 ÷ 30 = 3, one gets

  9. Betz's law - Wikipedia

    en.wikipedia.org/wiki/Betz's_law

    The power coefficient [9] C P (= P/P wind) is the dimensionless ratio of the extractable power P to the kinetic power P wind available in the undistributed stream. [ citation needed ] It has a maximum value C P max = 16/27 = 0.593 (or 59.3%; however, coefficients of performance are usually expressed as a decimal, not a percentage).
