What is the distance between the left and right stem lights on an inverted Y light pattern?

• A. 10 meters
• B. 14 meters
• C. 7 meters
• D. 20 meters

Answer: (B)

In an inverted Y light pattern, the left and right stem lights are placed symmetrically about the centerline, with each stem offset by 7 meters from the center. The distance between the two outer stems is then 7 meters plus 7 meters, totaling 14 meters. So the best answer is 14 meters. The other numbers would correspond to half the span or distances not matching this symmetric pattern.
