rxxvi FACULTY OF SCTFNCF THIRD YEAR Describe and illustrate by diagram tin form of tlie iflothermals of substance for teuij rrature it wliirh it ran exist partly in the liquid and partly in tin gaseous Mat Hence explain the strain line 'the water line and critical state Describe Carnot's cycle for heat engine and exprega the efficiency of the engine Show that all reversible engines have maximum efficiency Explain what is meant by 4entropy' and 4available energy Show that the greater the original entropy the smaller the available energy of body Explain how the wave theory of light accounts the phenomena of refraction and of total reflexion plane wave of light is transmitted normally through grating Explain the formation of tin4 spectra and show how grating and spectrometer may be used to measure the wave length of monochromatic light In what respect does spectrum produced by grating differ from that produced by prism Give general account of the phenomenon of the rotation of tin4 plane of polarisation of light state the laws relating to the phenomenon Explain the action of the hiqtiartz and nee deaeribe an instrument for the measurement of the rotation of the plane of polarisation On the supposition that electrostatic phenomena are due to dielectric strain explain electroet itic induction and the action of Ley den condenser Diecuee the theory that has been suggested to account for the phenomena magnetisation Shew how the theory accounts fur the changes of indm and residual magnetiHiii in magnetic subetance under increasing and decreasing monetising force
