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.
How is polymer fibers terminated? PMMA fiber single ends can be of some types always depending upon the nature of the conductor and the last application. A Simply cut fiber wit
Kirchhoff's rules (G.R. Kirchhoff): loop rule The total of the potential differences encountered in a round trip about any closed loop in a circuit is zero. point
(1) Standing pulse can be longitudinal / transverse. (2) The disturbance confined to a particular part among the starting point and reflecting point of the ray. (3) There is
3 scenarios: You have an object such as a jar, and you submerge it under water to 50m depth. (Every 10m down increases pressure by 1 bar, thus the pressure is 5 bar). Scenario 1:
Q. Give the differences between hard X-rays and soft X-rays.
In certain ranges of a piano keyboard, more than one string is tuned to the same note to provide extra loudness. For example, the note at 110 Hz has two strings at this frequency.
