Binding Energy and mass defect
Binding energy is the energy required to split the nucleus of an atom into neutrons and protons, while Mass defect is the difference b/w the predicted mass and the actual mass of the nucleus of an Atom. The binding energy of the system can appear as extra mass, which…

examples of total internal reflection
Total Internal Reflection One of the qualities of any optically transparent material is the speed at which light travels within the material, i.e., it depends upon the refractive index n of the material. The index of refraction is merely the…

Dual nature of matter and De broglie wavelength
What is dual nature of matter? Our mental views of waves and particles are drawn from familiarity with very large-scale objects such as tennis balls and ocean waves. Like paul Davies, physicist and science writer it is impossible to visualize…

Examples of mechanical and matter waves
Mechanical waves and matter waves are types of waves. The basic difference between mechanical and matter waves is that mechanical waves required a medium for propagation such as sound waves, while matter waves are the waves that contain information about…

Factors Affecting Resistance
Resistance is the property of the material that restricts the flow of electrons. There are four factors affecting resistance which are Temperature, Length of wire, Area of the cross-section of the wire, and nature of the material. When there is…

What are the 7 different Types of logic gates?
There are 7 types of logic gates which are: AND gate, OR gate, XOR gate, NAND gate, NOR gate, XNOR gate, and NOT gate. Logic gates are electronic circuits that make logical decisions. It has one output and one or more inputs. Output signal appears…

Difference between forward bias and reverse bias of semiconductor diode
The difference between forward bias and reverse bias is that in forward biasing positive terminal of the battery is connected with the p-type and negative terminal is connected with n-type of semiconductor, while in reverse biasing positive terminal of the…

Postulates of Bohr Atomic Model
Niels Bohr ( 10/7/1885 – 11/18/1962 ) was a Danish physicist and Nobel Prize known for his (fundamental) contribution to the development of atomic theory and quantum mechanics. Notable findings on the structure of the atom include three famous postulates of the Bohr atomic model based Rutherford atomic…

What are some examples of refraction of light?
“The process of bending of light as it passes from air into glass and vice versa is called refraction of light.”Mirage, bent pencil in a glass of water, rainbow, and sunset are some examples of refraction of light. Why does…
