Short Answer

An experiment was performed in which neutrons were shot through two slits spaced 0.10 mm apart and detected 3.5 m behind the slits. Figure P38.49 shows the detector output. Notice the scale on the figure. To one significant figure, what was the speed of the neutrons?

The resultant value is

Step by Step Solution

Step 1: Given information

Neutrons were fired through two slits spaced 0.10 mm apart and detected 3.5 m behind the slits in an experiment.

Step 2: Calculations

In a double slit experiment, we can start with an expression for fringe spacing.
