Brewster’s Law of Polarization of Light

Brewster’s Law: In 1811 Brewster’s proposed it. When Un-polarized light is incident at the angle called Brewster’s angle or angle of polarization, the light that is reflected from the surface is therefore perfectly polarized.
He was able to prove that the tangent of the angle of polarization is numerically equal to the refractive index of the medium.
That is....


 where is   refractive index of the medium and    is the polarization angle.
suppose, un-polarized light is incident at an angle equal to the polarizing angle on the glass surface(Denser medium). It is reflected along PB and refracted along PC.

Difference between Orbit and an Orbital:

Image
Orbit Orbital As postulated by Bohr, an orbit is a definite circular path at a definite distance from the nucleus in which the electron revolve round the nucleus. Orbits are designated by the capital letters K, L, M, N…. etc. As postulate by wave nature of an electron, an orbital is a three-dimensional region around the nucleus within which the probability of finding an electron is maximum., Orbital’s are designated by s, p, d… etc. Orbits are circular in shape. Orbital’s have different shapes. It represents the planer motion of the electron. It represents the three-dimensional motion of the electro round the nucleus. An orbit indicates an exact position of an electron in an atom. An orbital does not specify the exact position of an electron in an atom. The maximum number of electro in an orbit is equal to 2n^2, where n is the number of the orbit. An orbital cannot acco

Dalton's Atomic Theory

Image
Dalton's Atomic Theory In 1800, Dalton   postulate some theory for atom called Dalton’s atomic theory. They are given bellow: 1) All matter is made of atoms. Atoms are indivisible and indestructible. 2) All atoms of a given element are identical in mass and properties 3) Compounds are formed by a combination of two or more different kinds of atoms. 4) A chemical reaction is a rearrangement  of atoms.
