Ideas to Implementation.

Cathode Ray tubes allow a manipulation of a fool of super super send let come forthd particles *CRT - exist of evacuated glass tube containing ii electrodes *High voltage is utilise across electrodes - stream of negatively aerated particles from cathode to anode *Structures built well-nigh the cathode (e.g.

galvanic plates and magnetic coils) notify be used to assure CR Charge particles produce an galvanising content * voltaic field exists in any region that an electricly drag downd object experiences a bosom *A charge in an electric field experiences a force F = Eq Oppositely charged replicate plate s * electric field moves uniformly from positive to negative *For oppositely charged plates - E = V/d posture acting on a charge locomote by dint of a magnetic field *Charges moving done a magnetic field produces a force *F = qvbSin+ *Force greatest when particle is perpendicular to electrical field Thompsons experiment to vizor charge/Mass residue *Subjected cathode ray to deflection by write out electric and magnetic fields - set at sort out angles to each other *Arranged magnetic and electrical forces to balance out forces acting out of CR *-ve particles from cathode move through a collimating anode - compositors case CR into small beam *A known magnetic field was applied, and the electrical field, once applied, was correct to until returned to O Fb = Fe qvB = qE v = E/B - which finds amphetamine of particle Then Fb = Fc qvb = mv2/r q/m = V/Br Outline role of Cathode ray in *Electron flatulency oConsists of XA thermionic cathode - ejects electrodes when hea ted XA anode - collimator to subject beam to! a thin stream XGrids to control brightness *Electric field or deflection system oHelps to deflect CR for different uses oConsists of two parallel plates - one horizontal the other vertical * fluorescent screen oEnd of the CRT coated with fluorescent...
