W. L. Bragg gave a simple explanation for the study of crystal structure by using the phenomenon of diffraction and name it is as Bragg’s law.

Numerical integration is the method to calculate the approximate value of the integral by using numerical techniques.

These are those polymers which decompose under aerobic or anaerobic conditions, as a result of the action of microorganism/enzymes.

Crystal field theory established in 1929 explains the interaction of the metal ion and the ligand as a pure electrostatic reaction

Waterfall model needs requirements, design, implementation, testing and maintenance are phases of this methodology.

Chirality is an important property of asymmetry in many branches of science. A chiral molecule or ion exists in two stereoisomers that are mirror images of each other, called enantiomers

Polyvinyl chloride is produced from the main component. It is white, brittle solid material available in powder form or granules.

The unit test is white-box focused, and numerous components can be tested simultaneously.

Scrum is a particular kind of Agile framework. Scrum is a method of working that is iterative.

HTML stands for Hyper Text Markup Language, and it is the most extensively used programming language for creating web pages.

HTML tags are similar to keywords in that they specify how a web browser will format and display text.

Optical activity is the ability of a chiral molecule to rotate the plane of plane-polarised light.some organic compounds cause the rotation of polarized light

Elastomers are polymers showing properties of both viscosity and elasticity and are also called viscoelasticity. The molecules of elastomers held together by weak intermolecular forces

Biological Oxygen Demand (BOD) estimates the amount of biodegradable organic matter that is present in polluted waters, effluents and polluted waters

It is a theoretical model which details the molecular composition of the gas in terms of a huge number of sub microscopic particles that contain both atoms and molecules.

This method was given by Leonhard Euler. Euler’s method is the first order numerical method for solving ordinary differential equations with given initial value.

The characteristic equation is the equation which is used to find the Eigenvalues of a matrix. This is also called the characteristic polynomial.

The integration of a function of a complex variable along an open or close curve in the plane of the complex variables is known as complex integration. Cauchy’s integral theorem is the part of complex integration.

functions play an important role in mathematics. A function defines a specific correlation between the two data sets. Beta and gamma functions are from the group of Euler’s integral functions.

There are many applications of DSP in the present era. Such as in speech coding and compression, electrocardiography and many more.

Addressing modes are used to specify the data to be operated with the help of instructions.

Snubber Circuit is the one used for suppressing voltage spikes. These are energy absorbing circuits. RC circuits are basic snubber circuits.

Laplace Transform is a method used for solving differential equations. The Dirichlet condition defines the necessary condition for transform

The 8051 interrupts are INT0, INT1,TO ,T1 , TI/RI. All these interrupts are controlled by IE (interrupt enable) register.

A controller which controls the motor is called Variable Frequency Drive. By varying the frequency and voltage of supply it controls the motor

The main components of Phase Locked Loop are a phase detector with a voltage controlled oscillator. It also has loop filter feedback.

Whenever a signal is sampled below Nyquist rate (fs < 2B), the signal is called under sampled and the Aliasing effect hampers the results.

The Circular Convolution can be performed using two basic methods which are concentric circle method and matrix multiplication method.

curve tracing- a picture speaks more clearly than words and numbers. A curve which is the image of functional relationship gives us a lot information about the relation.

In order to make communication more safer and reliable digital signals are used. The basic digital modulation techniques are ASK, PSK,FSK and MSK
