An electron is in a box of width 3*10^-10m.what are de broglies wavlength and magnitude of momentum of the electron if it is inA)n=1 level B)n=2 level C)n=3 level
Ans) use the principe wavlength=2L/m
Wave-particle duality: The principle of quantum mechanics that implies that light (and, indeed, all other subatomic particles) sometimes work as a wave, and sometime like a pa
Regard as two Styrofoam cups. Each one is on the end of its own neutral slender glass rod which serves as a handle. One of the cups has a fixed amount of positive charge consistent
Microwave diathermy The microwave diathermy can be produced in special tube which can be placed several inches from the region to be treated . Microwave can penetrate deep int
One of the Maxwell's e-m equations involves the curl of the electric field. Write down the equation and mention the law of electromagnetism which is shown by the equation.
Electric field (intensity) is a vector number. Electric field because of a positive particle is always away from the charge and that because of a negative charge is always toward
