  2. Minimum deviation - Wikipedia

    en.wikipedia.org/wiki/Minimum_deviation

    In a prism, the angle of deviation (δ) decreases with increase in the angle of incidence (i) up to a particular angle.This angle of incidence where the angle of deviation in a prism is minimum is called the minimum deviation position of the prism and that very deviation angle is known as the minimum angle of deviation (denoted by δ min, D λ, or D m).

  3. Power (physics) - Wikipedia

    en.wikipedia.org/wiki/Power_(physics)

    Power is the rate with respect to time at which work is done; it is the time derivative of work: =, where P is power, W is work, and t is time.. We will now show that the mechanical power generated by a force F on a body moving at the velocity v can be expressed as the product: = =

  4. Dispersive prism - Wikipedia

    en.wikipedia.org/wiki/Dispersive_prism

    A ray trace through a prism with apex angle α. Regions 0, 1, and 2 have indices of refraction, , and , and primed angles ′ indicate the ray's angle after refraction.. Ray angle deviation and dispersion through a prism can be determined by tracing a sample ray through the element and using Snell's law at each interface.

  5. Larmor formula - Wikipedia

    en.wikipedia.org/wiki/Larmor_formula

    Working in CGS units, we first need to find the form of the electric and magnetic fields. The fields can be written (for a fuller derivation see Liénard–Wiechert potential) (,) = (()) + ([() ˙] ()) and =, where is the charge's velocity divided by , ˙ is the charge's acceleration divided by c, is a unit vector in the direction, is the magnitude of , is the charge's location, and = /.

  6. Faxén's law - Wikipedia

    en.wikipedia.org/wiki/Faxén's_law

    Faxén's law is a correction to Stokes' law for the friction on spherical objects in a viscous fluid, valid where the object moves close to a wall of the container. [ 4 ] See also

  7. Momentum - Wikipedia

    en.wikipedia.org/wiki/Momentum

    In Newtonian mechanics, momentum (pl.: momenta or momentums; more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object. . It is a vector quantity, possessing a magnitude and a directi

  9. Snell's law - Wikipedia

    en.wikipedia.org/wiki/Snell's_law

    Refraction of light at the interface between two media of different refractive indices, with n 2 > n 1.Since the velocity is lower in the second medium (v 2 < v 1), the angle of refraction θ 2 is less than the angle of incidence θ 1; that is, the ray in the higher-index medium is closer to the normal.
