Wave Propagation in Dilute Plasmas Subject: Physics In this section we consider wave propagation in an ionised plasma comprising ne electrons and rti ions per unit volume. In a dilute plasma we can ignore the (typically distant) ions as they provide little…
Standing waves on Open Circuited Lossless Transmission Line Subject: Physics Unless the line is terminated with the characteristic impedance there will also be reflected waves traveling in the —x direction, and the wave amplitude will be the sum of incident and reflected components. If the…
Electronegativity Subject: Chemistry The degree of ionic character in a covalent bond is determined by the electronegativity difference between the two elements bonded together. Electronegativity is the ability of an atom in a bond to attract electrons towards…
Transmission Lines Subject: Physics Transmission lines are electrical cables which consist of two parallel conductors of uniform cross section, usually separated by a dielectric, and which are designed to transmit radio frequency (≈kHz to ≈300 MHz) signals from one…
What is E-mail? Subject: Technology In short electronic mail is known as e-mail E-mail is a fast and efficient mode of communication with friends, classmates, relatives or colleagues through internet. There is no need of stamp, post card or envelope…
