Literally resonance means the phenomena of amplification that could be occurred when the frequency of an applied force in a harmonic proportion to the natural frequency on which it acts and the oscillation acts at the higher level or amplitude then the same force is applied at the other. Resonant frequency or resonance frequencies are … Read more

Reactance and impedance are different from each other as reactance refers to electrical resistance in which the opposition to the change in voltage which may be happening due to the capacitance or maybe in current due to inductive reactance in which the imaginary component of AC impedance. It also consists of magnetic reactance which is … Read more

What is the literal meaning of oscillation is the first question arises and answer to this is oscillation or oscillators are electronic circuits that generate a continue periodic waveform at a precise frequency another explanation is that oscillation can convert a DC into an AC output or can be called waveform which can have a … Read more

It is an electrical circuit consisting of an inductor that stands for L, capacitor which stands for C and resistor which stands for R which are connected in series or parallel. This name LCR is derived from the sequence of these letters used to denote the constituent components of this circuit. This circuit forms a … Read more

  Wattless current is a current which is mainly referred to as an AC current which contains only capacitor or inductor having zero power dissipation even though the current is flowing through it. In other words when current is flowing and there is no loss of power and when a pure inductor or pure capacitor … Read more

Total Internal Reflection of Light and its Applications Total internal reflection is referred to as the complete reflection of light rays within the given medium from the surrounding surface. Generally, the total internal reflection takes place at the boundary between two transparent mediums when the light ray in the medium of high refractive index is … Read more

The spherical mirrors are having the shape of a piece that is cut out of the spherical surface. The convex and concave mirrors are well-known examples of spherical mirrors. Makeup mirrors are the most common examples of concave mirrors. The term converging mirrors is also used for the concave mirror. These mirrors are known for … Read more

The mirror formula can be defined as a formula that describes the relationship between the distance of object u, a distance of image v, and the focal length of the mirror. The mirror formula is applicable for both spherical mirrors and plane mirrors. In mathematic form, it can be written as follows. When an object … Read more

When a ray of light is falling on any object either it is shiny, smooth, or polished, the light from that object bounces back these light rays into the eyes, and this is known as a reflection of light. This is the most important phenomenon as it allows us to look around the world. For … Read more

The equation relating to the distance of the object, focal length, and distance of image is known as lens formula. A common Gaussian form of thin lens formula is given below. The cartesian sign convention is also used due to its advantages with the more complex optical instruments and multiple lens systems. Both these forms … Read more
