Turning a laser, you shine the beam on an object located nearby and observe the interference pattern with a suitable infrared camera. By switching from a 1052 nm to a 1113 nm beam, you notice that you must move the laser 5.155 cm closer to the object to align the same order maxima and minima with their original locations on the object.
How far was the laser originally from the object in meters? Assume the small angle aprproximation applies.
