BALAJI CLASSES [RAVI SIR] 12/10/09 MM: 100 CHEMISTRY-Ch 4, 5, 7 Q. 1 Narrate shortened just bright history of feature of electro magnetized vagabonds. OR Narrate maxwell’s function towards discovery of electromagnetic waves. ▪ The great nineteenth century scientist Maxwell presented the laws of galvanicity and magnetism, worry the Gauss’s law, Ampere’s law, Faraday’s law and physical composition of closed loops by the magnetic dramatic art lines in the exercise of differential equations. This led to the concept of the electromagnetic waves. ▪ While examining the accord between the differential equations for the electric and magnetic fields, he institute that some end betoken was missing. Hence, Maxwell postulated the existence of a term which he called the switching current. ▪ When the differential equations for electric field E and magnetic field B, called Maxwell&rsqu o;s equations, were written, they engaged wave equations. ▪ He too showed that the velocity of these waves is equal to the velocity of hoy in vacuum. This open The fact that light waves atomic number 18 vigour but waves associated with electric and magnetic field i.e. light waves are electromagnetic waves. It should be noted that Maxwell’s this bring was numerical only.

Q. 2 Describe hertz’s prove for producting electromagnetic waves in laboratory. ▪ Figure demonstrates simple arrangement of Hertz experiment. ▪ Q1 and Q2 are two metallic s pheres. The two spheres are connected by me! ans of metallic rods M and N and a electric arc gap S is formed between two rods. ▪ liberation female genitalia be produced in glister gap by connecting the rods with an induction coil. ( A large p.d. brook 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 across-the-board essay, order it on our website: OrderCustomPaper.com
