Table of Contents Continuous Spectrum A spectrum is defined as a set of wavelengths that is a characteristic of electromagnetic radiation which is produced or absorbed by a specific object, substance, atom, or molecule. The colors of the rainbow, infrared radiation, ultraviolet radiation, and x-ray are few examples of the
Table of Contents Angular Momentum Angular momentum is referred to the property of any rotating object which is given by moment of inertia times angular velocity. It is described as the property of a rotating body which is further given by the product of the moment of inertia and the
Table of Contents Planck Quantum Theory According to Planck’s quantum theory; 1. Different atoms and molecules produce or absorb energy in discrete quantities only. The smallest amount of energy that can be emitted or absorbed by an electron in the form of electromagnetic radiation is termed as quantum. 2. The
Table of Contents Bohr Orbit Definition The Bohr model proposed that the electrons present in atoms revolve around the nucleus in a fixed path termed as bohr orbits or energy shells. In atomic physics, an atom is defined by the Bohr model as a small, positively charged nucleus that is
Table of Contents Electromagnetic Spectrum Definition In simple terms, the Electromagnetic spectrum can be defined as the range of all types of electromagnetic radiation and waves. All celestial bodies emit electromagnetic energy of different wavelengths. Mostly, electromagnetic waves tend to travel at speeds that is similar to the speed of
Table of Contents Emission Spectrum When electromagnetic radiations interact with atoms and molecules of matter, then the electrons present in these atoms may absorb energy and move to a higher energy state, losing their stability. To regain their stability, they then move from the higher energy state back to the
Table of Contents Bohr Model of Hydrogen Atom Equation Bohr Model of the hydrogen atom initially projected the planetary model, but later an assumption regarding the electrons was made. The assumption made was the quantization of the structure of atoms. Bohr’s projected that electrons revolved around the nucleus in specific
Table of Contents Bohr Model Bohr model of the atom was proposed by Neil Bohr in the year 1915. It was an extended modification of Rutherford’s model of an atom. Rutherford made the first discovery by presenting the model of an atom, in which he described that a nucleus (a
Table of Contents Photoelectric Effect Definition The photoelectric effect is referred to as a phenomenon in which electrons are ejected from the surface of a metal when light is incident on it. The electrons ejected are termed as photoelectrons. The emission of photoelectrons and the kinetic energy of the ejected
Table of Contents Quantum Number Definition Quantum numbers are often used to define the trajectory and the movement of an electron in an atom. Quantum numbers are defined as the set of numbers that are used to determine the position and energy of the electron in an atom. Types of
