BALAJI CLASSES [RAVI SIR] 12/10/09 MM: 100 CHEMISTRY-Ch 4, 5, 7 Q. 1 Narrate shortened just bright history of stemma of electro magnetised vagabonds. OR Narrate maxwell’s theatrical role towards discovery of electromagnetic waves. ▪ The great nineteenth century scientist Maxwell presented the laws of galvanisingity and magnetism, worry the Gauss’s law, Ampere’s law, Faraday’s law and physical composition of closed loops by the magnetic field of study lines in the exercise of differential equations. This led to the notion of the electromagnetic waves. ▪ While examining the accord betwixt the differential equations for the electric and magnetic fields, he institute that some end depute was missing. Hence, Maxwell postulated the existence of a term which he called the chemise current. ▪ When the differential equations for electric field E and magnetic field B, called Maxw ell’s equations, were written, they engaged wave equations. ▪ He to a fault showed that the velocity of these waves is equal to the velocity of hoy in vacuum. This ceremonious The fact that light waves atomic number 18 zero but waves associated with electric and magnetic field i.e. light waves argon electromagnetic waves. It should be noted that Maxwell’s this practice was numerical only.

Q. 2 Describe cps’s experiment for producting electromagnetic waves in laboratory. ▪ Figure demonstrates simple arrangement of Hertz experiment. ▪ Q1 and Q2 are two metallic spheres. The two sph! eres are committed by means of metallic rods M and N and a electric arc gap S is formed between two rods. ▪ liberation gouge be produced in release gap by connecting the rods with an induction coil. ( A large p.d. rouse 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 dependable essay, order it on our website: OrderCustomPaper.com
