If the electrons striking the target eject an electron from the K-shell of the atom, a vacancy is crated in the K-shell. Instantly an electron from one of the outer most shell, say L-shell jumps to the K-shell, emitting an X-ray photon of energy equal to the energy difference among the two shells. Likewise, if an electron from the M-shell jumps to the K-shell, X-ray photon of high power is emitted. The X-ray photons emitted because of the jump of electron from the L, M, N shells to the K-shells gives K?, K?, K? lines of the K-series of the spectrum.
If the electron striking the target ejects an electron from the L-shell of the target atom, an electron from the M, N ..... shells jumps to the L-shell so that X-rays photons of smaller power are emitted. These photons form the lesser energy emission. These photons form the L-type of the spectrum. In a similar way the formation of M type, N type etc. may be explained.
An ostrich can run at speeds of up to 72km/h. Suppose an ostrich runs 1.5km at the speed of 58 km/h and then runs another 1.5km at the speed of 29km/h. What is the ostrich average
VELOCITY- TIME GRAPH: The graphs which represents the variation of velocity of an object with respect to time is known as velocity- time graph.
Q Define: self inductance. The coefficient of self induction of a coil is numerically equivalent to the opposing emf induced in the coil when the rate of change of current thr
Explain idea of CPH comes up of what? Answer; Since 1962 I doubted on Newton's laws. I didn't accept the infinitive speed and I found un-vivid the laws of gravity and tim
Unit of Charges: The S.I unit of charge is Coulumb represented by "c".
It is an instrument used to detect small current passing by it by showing deflection. Galvanometers are of dissimilar types e.g. moving coil galvanometer, moving magnet galvanomete
Negative feedback principle: The idea that in a system where there are self-propagating conditions, those new conditions tend to act against earlier existing circumstances. Su
How many types of fibers are there? There is truly only one fiber optic. The word "fiber optics" applies really to a stem of light physics dealing along with the properties of
APPLICATIONS OF NEWTON'S LAWS - II 1. As the body moves through the body it displaces the fluid. It has to exert a force on the fluid to push it out of the path. By the Newto
