The Mach-Zehnder interferometer pictured below has side lengths of 23 cm and 46 cm, the light has a wavelength of 500 nm. Reflection from the beam-splitter introduces a phase shift of =4,
whilst transmission through beam splitters and reflection from mirrors have zero phase shift..

Alow cost, low earth orbit (leo) satellite is to be fabricated at a university, for subsequent launch by rocket. what are the constraints and objectives for selection of a material suitable for the satellite bus (i.e. the structure)? explain each in brief. (15 marks) b)suggest sources of data which could support the selection of materials for applications in space. (5 marks) c) set weights for the objectives listed in (2a) using the digital logic method. (5 marks)
