An important experimental device that uses interference is the Michelson interferometer. Michelson interferometers are used to make precise measurements of wavelengths and of very small distances. A Michelson interferometer takes monochromatic light from a single source and divides it into two waves that follow different paths. Interference occurs when the two light waves are recombined. The figure below shows the principal components of a Michelson interferometer. A ray of light from a monochromatic source A strikes the beam splitter C,...

Q3: The distillation column shown in the figure below is used to distill a binary mixture. Symbols x, y, z denote mole fractions of the more volatile component, while B, D, R, and F represent molar flow rates. It is desired to control distillate composition y despite disturbances in feed flow rate F. All flow rates can be measured and manipulated with the exception of F, which can only be measured. A composition analyzer provides measurements of y. (a) Propose...
