  2. Prism correction - Wikipedia

    en.wikipedia.org/wiki/Prism_correction

    Prentice's rule, named so after the optician Charles F. Prentice, is a formula used to determine the amount of induced prism in a lens: = where: P is the amount of prism correction (in prism dioptres) c is decentration (the distance between the pupil centre and the lens's optical centre, in millimetres)

  3. Decay correction - Wikipedia

    en.wikipedia.org/wiki/Decay_correction

    The formula for decay correcting is: = where A 0 {\displaystyle A_{0}} is the original activity count at time zero, A t {\displaystyle A_{t}} is the activity at time "t", "λ" is the decay constant , and "t" is the elapsed time.

  4. Bolometric correction - Wikipedia

    en.wikipedia.org/wiki/Bolometric_correction

    Bolometric correction. In astronomy, the bolometric correction is the correction made to the absolute magnitude of an object in order to convert its visible magnitude to its bolometric magnitude. It is large for stars which radiate most of their energy outside of the visible range. A uniform scale for the correction has not yet been standardized.

  6. Cauchy's equation - Wikipedia

    en.wikipedia.org/wiki/Cauchy's_equation

    It deviates in the ultraviolet and infrared regions. In optics, Cauchy's transmission equation is an empirical relationship between the refractive index and wavelength of light for a particular transparent material. It is named for the mathematician Augustin-Louis Cauchy, who originally defined it in 1830 in his article "The refraction and ...

  7. Hypsometric equation - Wikipedia

    en.wikipedia.org/wiki/Hypsometric_equation

    Formulation. The hypsometric equation is expressed as: [1] where: h {\displaystyle h} = thickness of the layer [m], z {\displaystyle z} = geometric height [m], R {\displaystyle R} = specific gas constant for dry air,

  8. Eötvös effect - Wikipedia

    en.wikipedia.org/wiki/Eötvös_effect

    The force of gravity and the normal force. The resultant force acts as the required centripetal force. The mathematical derivation for the Eötvös effect for motion along the Equator explains the factor 2 in the first term of the Eötvös correction formula. What remains to be explained is the cosine factor.

  9. Brus equation - Wikipedia

    en.wikipedia.org/wiki/Brus_equation

    The overall equation is [3] Egap, me *, and mh * are unique for each nanocrystal composition. For example, with cadmium selenide (CdSe) nanocrystals: Egap (CdSe) = 1.74 eV = 2.8·10 −19 Joules, me * (CdSe) = 0.13 me = 1.18·10 −31 kg, mh * (CdSe) = 0.45 me = 4.09·10 −31 kg.

  10. Esophoria - Wikipedia

    en.wikipedia.org/wiki/Esophoria

    Esophoria is an eye condition involving inward deviation of the eye, usually due to extra-ocular muscle imbalance. It is a type of heterophoria. Cause. Causes include: Refractive errors; Divergence insufficiency; Convergence excess; this can be due to nerve, muscle, congenital or mechanical anomalies.

  11. Šidák correction for t-test - Wikipedia

    en.wikipedia.org/wiki/Šidák_correction_for_t-test

    Šidák correction for t-test. One of the application of Student's t-test is to test the location of one sequence of independent and identically distributed random variables. If we want to test the locations of multiple sequences of such variables, Šidák correction should be applied in order to calibrate the level of the Student's t-test.
