Reflection of light Reflection of light refers to the bouncing back of light when it encounters a surface. It follows the law of reflection, which states that the angle of incidence is equal to the angle of reflection, with both angles measured with respect to the normal (a line perpendicular to the surface at the…
Optics Optics is a branch of physics that deals with the study of light and its behavior. It focuses on understanding how light interacts with various objects and materials. Optics can be divided into two main branches: Optics has wide-ranging applications in various fields, including astronomy, photography, medicine (such as in ophthalmology and microscopy), telecommunications…
Electromagnetic Spectrum The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. It encompasses a wide range of wavelengths and includes various types of electromagnetic waves, each with its own unique properties and applications. The electromagnetic spectrum is divided into different regions based on the wavelength or frequency of the waves. These…

Displacement current Displacement current is a concept in electromagnetism that was introduced by James Clerk Maxwell in his equations describing the behavior of electric and magnetic fields. It is a term used to explain the relationship between changing electric fields and magnetic fields. Displacement current arises when there is a time-varying electric field in a…
Electromagnetic waves Electromagnetic waves are a fundamental concept in physics that describe the propagation of electromagnetic radiation through space. They consist of oscillating electric and magnetic fields that are perpendicular to each other and to the direction of wave propagation. Here are some key points about electromagnetic waves: Understanding electromagnetic waves is crucial in fields…
Transformer A transformer is an electrical device used to transfer electrical energy between two or more circuits through electromagnetic induction. It consists of two or more coils of wire, called the primary and secondary windings, that are wound around a common core. Key points about transformers: It’s important to note that transformers are a broad…
AC Generator An AC generator, also known as an alternator, is a device that converts mechanical energy into electrical energy in the form of alternating current (AC). It is commonly used in power plants and electric generators. Key components and working principle of an AC generator: AC generators play a crucial role in providing electrical…
Power in AC circuits Power in AC (alternating current) circuits is a key concept that relates to the flow of electrical energy. In AC circuits, the voltage and current alternate periodically, resulting in a sinusoidal waveform. The instantaneous power in an AC circuit can be calculated using the following formula: Instantaneous power (P) = Voltage…
LCR Series circuit An LCR series circuit is an electrical circuit that consists of three components connected in series: an inductor (L), a capacitor (C), and a resistor (R). Here are some important aspects of an LCR series circuit: Understanding these aspects of an LCR series circuit is important for analyzing its behavior, calculating parameters…
