Ray Optics is a branch of optics that describes light propagation in the form of rays. Ray Optics is also called geometrical optics which deals with the geometry of falling lights. this article is about refraction, its laws, refraction through glass slab and its various causes, and practice tracing the path of light rays passing through glass slab. Refraction is the property of the change in direction of the wave while entering from one medium to another medium. This change in direction is due to a change in the speed of the wave....
Usually while studying the theory behind the electrical circuits it is assumed that all the components of the circuits are ideal. In an ideal state, the battery of the system is assumed to have zero resistance. But in reality, it is not the case. While working with batteries in real life, it s noticed that they have some internal resistance which affects the current in the circuit. Sometimes it is not specified on the battery and it changes as the battery discharges. In that case, it becomes essential to calculate the internal resistance of the battery being used. Let’s look at how it’s done in detail....
Paramagnetic Materials are those materials that get weakly magnetized when exposed to the external magnetic field. The spin of the paramagnetic materials are randomly oriented and they get arranged in the direction of the external magnetic field. They lose their magnetic properties when the external magnetic field is removed. Paramagnetic Materials are important in the field of material science as they are used for various applications...
Electrical potential energy is the cumulative effect of the position and configuration of a charged object and its neighboring charges. The electric potential energy of a charged object governs its motion in the local electric field....
Moving charges is an electric current that passes through a fixed point in a fixed period of time. Moving charges are responsible for establishing the magnetic field. The magnetic field is established due to the force exerted by the flow of moving charges. As the magnetic field is established moving charges start acting like a magnet....
CBSE Class 12 Physics Notes are an essential part of the study material for any student wanting to pursue a career in engineering or a related field. Physics is the subject that helps us understand our surroundings using simple and complex concepts combined. Class 12 physics introduces us to a lot of such topics that are related to our daily lives, but yet we don’t understand the concepts behind them....
Laws of Refraction of Light are the basic laws which govern the refraction of light. As we know light changes its path when it changes its medium and this property is called the refraction of light. The laws of refraction of light are useful in defining the relationship between incident light and refracted light....
Mirror and magnification formulas are fundamental equations used in optics to describe the formation of images by mirrors. These formulas are commonly applied in geometrical optics, which deals with the behavior of light rays using the principles of geometry. This article contains mirror and magnification formula and problems based on it in detail....
NEET Syllabus 2024 is released by the National Testing Agency (NTA) along with the official notification on its website. It is anticipated that the latest syllabus for the year 2024 will closely resemble the current one. The NEET (National Eligibility cum Entrance Test) serves as the principal entry point for aspiring medical students throughout India. The NEET syllabus encompasses subjects such as Physics, Chemistry, and Biology, with a focus on fundamental concepts from the 11th and 12th-grade course materials....
Frequency Modulation or FM is a method of encoding information on one carrier wave by changing the wave carrier frequency. Frequency Modulation technology is used in the fields of computing, telecommunications, and signal processing. In frequency modulation, the frequency of the carrier wave is changed according to the frequency of the modulating signal....
Lenz law was given by the German scientist Emil Lenz in 1834 this law is based on the principle of conservation of energy and is in accordance with Newton’s third law. Lenz law is used to give the direction of induced current in the circuit....
The topic of induction was first given by Oersted by discovering that a magnetic field is produced through an electric field. After this, different scientists started to think can the reverse is possible .i.e. can we produce electric current from a magnetic field....
