The first use of new hologram technology to train doctors Holography is a technique used to create a three-dimensional image of an object or a scene by recording and reconstructing the light scattered from it. The term “hologram” typically refers to a flat, two-dimensional image that, when viewed under appropriate lighting conditions, appears to be three-dimensional. Holography was first invented in the 1940s and has been used for a variety of applications since then, including security features on credit cards and passports, as well as scientific and artistic purposes. Recent advances in technology have made it possible to create holograms that can be seen without the use of special glasses or a laser. For example, there are now holographic displays that use light-emitting diodes (LEDs) and computer algorithms to create the illusion of a 3D object floating in space. Holography is still a developing field, and there is ongoing research into how to create more sophisticated a...

What is the skin effect? Answer: Kshin effect: AC current flows through a conductor The surface for religion that does not enter inside the conductor while being Trying to flow through it is called the skin effect. What are the effects of skin effect on transmission lines? Answer: The effects of skin effect are: There is power loss in the line. The skin effect also increases as the diameter of the line increases. Skin on size of conductor in transmission line Depends on the effect. Depends on the conductor material. What is puncture voltage? Answer: The voltage at which the insulation of the insulator is completely broken It is called puncture voltage. What is flash-over voltage? Answer: If the voltage is increased, then the dielectric strength of air dissipates and causes severe electrical flashes. This voltage Flash-over voltage is called. Skin effect depends on what factors. Answer: Generally skin effect depends on On quality of Conductor material: Skin effect is more in case of...

What is transistor called? How many types and what are they? Answer: A block is opposite to N or P type semiconductor As a result of sandwiching between two semiconductors (ie two Ptype One of these is N-type or one of two N-types is P-type). The new device that is available is called Transistor. There are two types of transistors. Namely: (i) Bipolar junction transistor. (ii) Unipolar junction transistor. There are two types of B.J.T. Namely: a) PNP Transistor. (b) NPN Transistor. 2. Define: Emitter, Base, collector. Ans: Emitter : This part is much higher than other parts Amount doping is done. Its main function is majority Supply to charge carrier base. Base: It is located between and compared to other parts Very thin and very lightly doped. Collector: Its main function is majority charge This collector part is larger than the emitter part by passing the carrier is of size. What is Transistor Biasing? Its types? Transistor Why is Biasing done?  Answer: Transistor biasing: Trans...

  SP.N junction or P.N junction diode et semiconductor What is conductor diode?Answer: P.N junction: A P-type semiconductor is a Connection with N-type Semi-conductorIf done, the junction is created. It is called P.N junction.An electronic device that occurs like this is called a P.N junction diodeSemi-conductor diode is called. Junction making time is as follows Things happen or1. A thin depletion layer is formed. 2. A barrier potential is created across the junction. 3. The growth of the depletion layer depends on the junction and On Capacity.
