Step 1
Describe a procedure for the student to find the value of $d$
Answer
- Position the Set-Square: Place a set-square vertically under the radiation detector, making sure it is parallel to the detector's position.
- Align the Open End of Source: Adjust the position of the sealed source so that its open end aligns with one edge of the set-square.
- Measure the Distance : Use a ruler to measure the distance from the bottom of the set-square (in contact with the bench) to the open end of the source. This measurement gives the value of .
- Annotate Figure 1: On Figure 1, indicate the set-square's position relative to the detector and the source, clearly marking the height for clarity.
