For other uses, see Microwaves (disambiguation) . A telecommunications tower with a variety of dish antennas for microwave relay links on Frazier Peak , Ventura County, California . The atmospheric attenuation of microwaves and far infrared radiation in dry air with a precipitable water vapor level of 0.001 mm. The downward spikes in the graph correspond to frequencies at which microwaves are absorbed more strongly. This graph includes a range of frequencies from 0 to 1 THz; the microwaves are the subset in the range between 0.3 and 300 gigahertz. Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter; with frequencies between 300 MHz (100...

Orphan blocks (purple) exist outside of the main chain. Bitcoin network data A blockchain , [1] [2] [3] originally block chain , [4] [5] is a continuously growing list of records , called blocks , which are linked and secured using cryptography . [1] [6] Each block typically contains a hash pointer as a link to a previous block, [6] a timestamp and transaction data. [7] By design, blockchains are inherently resistant to modification of the data. The Harvard Business Review describes it as "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way". [8] For use as a distributed ledger...
Type of capacitors CONTRIBUTORS: JIMB0 FAVORITE 42 SHARE Share on Twitter Share on Facebook Pin It Introduction A capacitor is a two-terminal, electrical component. Along with resistors and inductors, they are one of the most fundamental passive components we use. You would have to look very hard to find a circuit which didn’t have a capacitor in it. What makes capacitors special is their ability to store energy ; they’re like a fully charged electric battery. Caps , as we usually refer to them, have all sorts of critical applications in circuits. Common applications include local energy storage, voltage spike suppression, and complex signal filtering. Covered in this Tutorial In this tutorial, we’ll be examining all sorts of capacitor-related topics, including: How a capacitor is made How a capacitor works Units of capacitance Types of capacitors How to recognize capacitors How cap...
