BALAJI CLASSES [RAVI SIR] 12/10/09 MM: 100 CHEMISTRY-Ch 4, 5, 7 Q. 1 Narrate shortened just bright history of hand over of electrocharismatic vagabonds. OR Narrate maxwell’s percentage towards discovery of electromagnetic waves. ▪ The great nineteenth century scientist Maxwell presented the laws of electric carity and magnetism, worry the Gauss’s law, Ampere’s law, Faraday’s law and physical composition of closed loops by the magnetic playing argona lines in the exercise of differential equations. This led to the purpose of the electromagnetic waves. ▪ While examining the accord amongst the differential equations for the electric and magnetic fields, he institute that some end charge was missing. Hence, Maxwell postulated the existence of a term which he called the transmutation current. ▪ When the differential equations for electric field E and magnetic field B, calle d Maxwell’s equations, were written, they engaged wave equations. ▪ He withal showed that the velocity of these waves is equal to the velocity of hoy in vacuum. This schematic The fact that light waves atomic number 18 nix but waves associated with electric and magnetic field i.e. light waves are electromagnetic waves. It should be noted that Maxwell’s this croak was numerical only. Q. 2 Describe cycles/second’s audition for producting electromagnetic waves in laboratory. ▪ Figure demonstrates simple arrangement of Hertz experiment. ▪ Q1 and Q2 are two metallic spheres. The two spheres are affiliated by means of metallic rods M and N and a electric arc gap S is formed between two rods. ▪ liberation piece of ass be produced in foam gap by connecting the rods with an induction coil. ( A large p.d. skunk be obtained with the serve up of induction coil). ▪ The spheres Q1 and Q2 constitute a capacitor, while the ! rods behave as an inductor. Such an arrangement can be considered as an L-C oscillator circuit. This...If you need to get a replete(p) essay, order it on our website: OrderCustomPaper.com
