  2. Marginal rate of technical substitution - Wikipedia

    en.wikipedia.org/wiki/Marginal_rate_of_technical...

    Thus the MRTS is the absolute value of the slope of an isoquant at the point in question. When relative input usages are optimal, the marginal rate of technical substitution is equal to the relative unit costs of the inputs, and the slope of the isoquant at the chosen point equals the slope of the isocost curve (see conditional factor demands ...

  3. Marginal rate of substitution - Wikipedia

    en.wikipedia.org/wiki/Marginal_rate_of_substitution

    Under the standard assumption of neoclassical economics that goods and services are continuously divisible, the marginal rates of substitution will be the same regardless of the direction of exchange, and will correspond to the slope of an indifference curve (more precisely, to the slope multiplied by −1) passing through the consumption bundle in question, at that point: mathematically, it ...

  4. Isocost - Wikipedia

    en.wikipedia.org/wiki/Isocost

    Now since the absolute value of the slope of the isocost line is the input cost ratio /, and the absolute value of the slope of an isoquant is the marginal rate of technical substitution (MRTS), we reach the following conclusion: If the isoquants are smooth and convex to the origin and the cost-minimizing input bundle involves a positive amount ...

  5. Elasticity of substitution - Wikipedia

    en.wikipedia.org/wiki/Elasticity_of_substitution

    Elasticity of substitution is the ratio of percentage change in capital-labour ratio with the percentage change in Marginal Rate of Technical Substitution. [1] In a competitive market, it measures the percentage change in the two inputs used in response to a percentage change in their prices. [2]

  6. Radiant intensity - Wikipedia

    en.wikipedia.org/wiki/Radiant_intensity

    Radiant intensity is used to characterize the emission of radiation by an antenna: [2], = (), where E e is the irradiance of the antenna;; r is the distance from the antenna.; Unlike power density, radiant intensity does not depend on distance: because radiant intensity is defined as the power through a solid angle, the decreasing power density over distance due to the inverse-square law is ...

  7. MRTS - Wikipedia

    en.wikipedia.org/wiki/MRTS

    The abbreviation MRTS is most commonly used to refer to Mass Rapid Transit System. The abbreviation MRTS may also refer to: Chennai Mass Rapid Transit System, ...

  8. Luminous energy - Wikipedia

    en.wikipedia.org/wiki/Luminous_energy

    This is sometimes called the quantity of light. [1] Luminous energy is not the same as radiant energy , the corresponding objective physical quantity . This is because the human eye can only see light in the visible spectrum and has different sensitivities to light of different wavelengths within the spectrum.

  9. Birks' law - Wikipedia

    en.wikipedia.org/wiki/Birks'_Law

    The relation is: = +. where L is the light yield, S is the scintillation efficiency, dE/dx is the specific energy loss of the particle per path length, k is the probability of quenching, [1] and B is a constant of proportionality linking the local density of ionized molecules at a point along the particle's path to the specific energy loss; [1] "Since k and B appear only as a product, they act ...
