D.E. of lines, passing through the origin, is

a) Define a wave front. b) Draw the diagram to show the shape of plane wave front as they pass through (i) a thin prism and (ii) a thin convex lens. State the nature of refracted wave front. c) Verify Snell’s law of refraction using Huygens’s principle

When a system is taken from A to C through path ABC, 10 J of heat flows to the system and 4 J of work is done by the system. How much heat flows into the system in path ADC, if the work done by the system is 3 J ?
