introduction to quantum mechanics

Introduction - Biomolecules are complex organic molecules. These molecules form the basic structural constituent of a living cell. The organic compounds such as amino acids, nucleotides and monosaccharides serve as building blocks of complex biomolecules. The important biomolecules are pr..

Uniform Motion - Introduction - Mechanics, the oldest physical science, is the study of motion of objects. It is applied in calculation of the path of an artillery shell, a space probe sent from earth to Mars, etc. Everything in the universe is in motion, from the tiny electrons..

Mechanics, the oldest physical science, is the study of motion of objects. It is applied in calculation of the path of an artillery shell, a space probe sent from earth to Mars, etc. Everything in the universe is in motion, from the tiny electrons to the giant galaxies. The study of motio..

Introduction - Animals are different from plants because of their ability of locomotion. This ability probably developed as they have to search for food, unlike the plants that are autotrophic. Since they move from place to place, the animals have to continuously encounter changes in thei..

Introduction - Organic compounds are isolated either from natural sources or from reaction mixtures. These compounds are seldom pure and are usually contaminated with small amounts of other similar compounds, which are found to exist together or formed during the reaction. In order to cha..

Introduction - We have seen in the previous lesson that a current carrying conductor when kept in a magnetic field experiences forces and torques. Is reverse phenomenon possible? If we rotate the coil in a magnetic field, will current flow in the coil without we passing it? The answer is ..

Summary - Heredity may be defined as the transmission of characteristics through generations Variation may be defined as differences among individuals of a species Both heredity and variation play important roles in evolution of organisms The study of the mechanism of transmission of char..

states that one quantum is absorbed by the molecule responsible for the primary photochemical process. After absorption, the excited molecule can then undergo various reactions. It can form a product, it can catalyze a chain reaction, or it can get de-excited. If on absorption of one ph..

Introduction - In the physical world, one of the most common phenomena is motion. The branch of Physics, which deals with the behaviour of moving objects, is known as mechanics. Mechanics is further divided into two sections namely Kinematics and Dynamics. Kinematics d..
