An interferometer is an instrument that uses interference effects to makevery precise measurements of small changes in distance.Figure QB3a shows the set-up of a simple interferometer. The lightproduced by the laser (λ = 700 nm) travels to the beam splitter, C (a halfsilvered mirror), where 50% of the laser light travels straight throughwithout changing direction (beam 1) and the other 50% is reflected(beam 2).Beam 1 hits mirror A and returns to the beam splitter, where it is thenreflected towards the screen (D). Beam 2 hits mirror B and returns tothe beam splitter, where it then travels straight through without changingdirection, also reaching the screen.All parts of the interferometer are suitably enclosed such that the onlylight inside the device comes from the laser.(i) Assuming that AC and BC are the same length, explain what youwould expect to observe on the screen and why.(ii) The interferometer set-up is modified such that the length of BCis 0.000525 mm longer than the length…
