  2. Prism correction - Wikipedia

    en.wikipedia.org/wiki/Prism_correction

    Thus a prism of 1 Δ would produce 1 cm visible displacement at 100 cm, or 1 meter. This can be represented mathematically as: = ⁡ where is the amount of prism correction in prism dioptres, and is the angle of deviation of the light.

  3. Quantum tunnelling - Wikipedia

    en.wikipedia.org/wiki/Quantum_tunnelling

    Introduction to the concept. Quantum tunnelling falls under the domain of quantum mechanics. To understand the phenomenon, particles attempting to travel across a potential barrier can be compared to a ball trying to roll over a hill. Quantum mechanics and classical mechanics differ in their treatment of this scenario.

    The Klein–Gordon equation and the Dirac equation are two such equations. The Klein–Gordon equation, The Klein–Gordon equation, − 1 c 2 ∂ 2 ∂ t 2 ψ + ∇ 2 ψ = m 2 c 2 ℏ 2 ψ , {\displaystyle -{\frac {1}{c^{2}}}{\frac {\partial ^{2}}{\partial t^{2}}}\psi + abla ^{2}\psi ={\frac {m^{2}c^{2}}{\hbar ^{2}}}\psi ,}

  6. Eyring equation - Wikipedia

    en.wikipedia.org/wiki/Eyring_equation

    The Eyring equation (occasionally also known as Eyring–Polanyi equation) is an equation used in chemical kinetics to describe changes in the rate of a chemical reaction against temperature. It was developed almost simultaneously in 1935 by Henry Eyring, Meredith Gwynne Evans and Michael Polanyi.

  7. Refractive index - Wikipedia

    en.wikipedia.org/wiki/Refractive_index

    Refractive index. In optics, the refractive index (or refraction index) of an optical medium is a dimensionless number that gives the indication of the light bending ability of that medium. The refractive index determines how much the path of light is bent, or refracted, when entering a material.

  8. Collision theory - Wikipedia

    en.wikipedia.org/wiki/Collision_theory

    nB is the number density of B in the gas in units of m −3. E.g. for a gas mixture with gas A concentration 0.1 mol⋅L −1 and B concentration 0.2 mol⋅L −1, the number of density of A is 0.1×6.02×10 23 ÷10 −3 = 6.02×10 25 m −3, the number of density of B is 0.2×6.02×10 23 ÷10 −3 = 1.2×10 26 m −3.

  11. 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.
