what is balmer series
Balmer series (J. Balmer; 1885): An equation that explains the emission spectrum of hydrogen whenever an electron is jumping to the next orbital; four of the lines are in visible spectrum, and the remainder (residue) are in the ultraviolet.
Tardon: A particle that has a positive real mass and travels at a speed very less than c in all inertial frames.
Zeeman Effect: Zeeman line splitting (P. Zeeman; 1896): Zeeman Effect is the splitting of lines in a spectrum whenever the source is exposed to the magnetic field.
Schwarzschild radius: The radius ‘r’ of the event horizon for a Schwarzschild black hole of mass m is specified by (in geometrized units) r = 2 m. In its conventional units:
r = 2 G m/c^{2}
Gauss' law for magnetic fields (K.F. Gauss): The magnetic flux via a closed surface is zero (0); no magnetic charges present; in its differential form,
div B = 0
Weak equivalence principle: principle of uniqueness of freefall: The idea in general relativity is that the world-line of a freefalling body is sovereign of its composition, structure, or state. This principle, hold by Newtonian mechanics and gravitat
Refraction law: For a wave-front travelling via a boundary among two media, the first with a refractive index of n_{1}, and the other with one of n_{2}, the angle of incidence theta is associated to the angle of refraction phi by:
The velocity of a body was observed to be constant throughout five minutes of its motion. Determine its acceleration during this interval?
Write down any two elementary particles that have nearly infinite life time?
Coanda effect: The effect which points out that a fluid tends to flow all along a surface, instead of flowing via free space.
