Imagine a vibrating pipe that moves 0.20 mm to either side of its equilibrium position. We can say that this motion will be visible if it is greater than the width of the central maximum found by treating the eye as a single slit. For a person 2.7 m away with an eye width of 1 cm viewing at roughly 550 nm, will the pipe’s motion be visible? (You can use the small-angle approximation if necessary.)

The angular width of the pipes motion 0000148 radians is smaller than the angular width of t... View the full answer
