Positive rays are sometimes called as the canal waves. These were found by Goldstein. If the cathode of a discharged tube has holes in it and the pressure of the gas is around 10-3 mm of Hg then faint luminous glow comes out from every hole on the backside of the cathode. It is supposed positive pulses which are rolling out from the holes.
Origin of positive rays: When potential dissimilarity is applied across the electrodes, electrons are gone from the cathode. As they move in the direction of anode, they gain power. These energetic electrons when hit with the atoms of the gas in the discharge tube, they ionize the atoms. The positive ions so formed at several places between cathode and anode travel towards the cathode. As during their motion, the positive ions when arrives the cathode, some pass by the holes in the cathode. These branches are the positive pulses.
A charge of 2.00x 10 -6 C is moved against a constant electric field. If 4.50 x 10 -4 J of work is done on the charge. what is the potential difference between the initial an
Consider an x-ray tube in which electrons are accelerated by a constant high voltage of 250 kV. If the electron beam current is 10 mA, calculate the x-ray energy flux (energy fluen
State Huygens' Principle. With the help of a suitable diagram, prove Snell's law of refraction using Huygens' Principle.
Although it needs not concern us further, we also consider that the flow is irrotational. To check for this property, let a tiny grain of dust goes with the fluid. Although this te
