Introduction Diffraction of X-rays by crystal is explained by Bragg’s law. This tutorial unwraps the unique diffraction observation in crystal lattice materials when X-rays pass through them. Diffraction is a universal principle when any wave passes from one medium to another. But X-ray diffraction (known short as XRD) has unique strength and is used in many applications. The underlying principle in this phenomenon is Bragg’s law which is addressed extensively in this tutorial. What Is Bragg’s Law? When X-rays are allowed to pass through a crystal lattice, the rays are scattered due to refraction. The Bragg’s law states that ... Read More

Introduction Diffraction of light waves is an important concept of wave optics. The phenomena of light, reflection and refraction can be explained only on the basis of wave optics. The direction in which the light propagates in the form of a wave is indicated by the light screen itself. When a stone is dropped on a motionless surface of the water, ripples spread around the area where the stone falls. This event is a perfect example of a wave spreading. As the ripple passes a particular point, the water molecules or particles at that point move up and down ... Read More

Introduction Measuring diameter of a small spherical body using vernier calliper has many practical applications in our daily life. Measurements are fundamental to all scientific sections. It also plays a crucial role in our daily life. Seeing your height, buying milk for your house. Actions like timing your friend in a race require measurements. Measurement answers questions, like how long, how heavy, and how fast. Measurement is the act of comparing an attribute or phenomenon of one object to the attribute or phenomenon of another object and assigning a numerical value to that object or phenomenon. Measurement is ... Read More

Introduction LCR Series Circuit has many applications. In electronics, components can be divided into two main classifications namely active and passive components. Resistors, capacitors, and inductors are some of the passive components. The combination of these components gives RC, RL, LR, LC, and LCR circuits. An RC circuit comprises a resistor and a capacitor. An RL circuit includes a resistor and an inductor. In an LR circuit, an inductor and resistor are connected together. Also, an LC circuit, an inductor, and a capacitor are joints. LCR is the abbreviation for L- inductance, C-capacitance, and R- resistance. An LCR circuit comprises ... Read More

Introduction Gross error, systematic error and random error are different types of errors. The error may be defined as the difference between the true value and the measured value. The actual value is the average value of multiple times the measured value. The measurement taken by the observer as accurately as possible is called a measured value. The quantities which we generally measure may be mass, length, time, volume, temperature, current, degree, etc. in all these cases observation finally reduces to the reading of a scale or noting the coincidence between two marks. As the personal judgment of the observer ... Read More
