Candela ROYGBIV Frequency Reflected Transmitted Brightness Transverse Dispersion Max Planck explained that light can be a particle and a wave. Light exhibits various characteristics. As a wave, it is a . of vibration and propagation. wave in terms of direction of light depends on the source and the distance from the source. L The electromagnetic waves are This is expressed in the unit of , arranged in the electromagnetic spectrum according to increasing Among the waves, the perceptible wave is the visible light. Visible light is composed of different colors abbreviated as colors of the rainbow. This has been proved by Sir Isaac Newton in which he used a prism to separate white light into its component colors. This phenomenon is called . light L- also known as the . The color of an object we see depends on or 1. 2. 3. 4. 5. 6. 7. 8.
Quantum mechanics and hydrogen atom
Consider an electron of mass m moves with the velocity v in a hydrogen atom. If an electron is at a distance r from the proton, then the potential energy function of the electron can be written as follows:
Isotopes of Hydrogen Atoms
To understand isotopes, it's easiest to learn the simplest system. Hydrogen, the most basic nucleus, has received a great deal of attention. Several of the results seen in more complex nuclei can be seen in hydrogen isotopes. An isotope is a nucleus of the same atomic number (Z) but a different atomic mass number (A). The number of neutrons present in the nucleus varies with respect to the isotope.
Mass of Hydrogen Atom
Hydrogen is one of the most fundamental elements on Earth which is colorless, odorless, and a flammable chemical substance. The representation of hydrogen in the periodic table is H. It is mostly found as a diatomic molecule as water H2O on earth. It is also known to be the lightest element and takes its place on Earth up to 0.14 %. There are three isotopes of hydrogen- protium, deuterium, and tritium. There is a huge abundance of Hydrogen molecules on the earth's surface. The hydrogen isotope tritium has its half-life equal to 12.32 years, through beta decay. In physics, the study of Hydrogen is fundamental.
