(3) Never shine a green laser at anyone, especially not at an airplane, since the pilots can see the beam. Some fool did this in 2002, and the F. B. I. arrested him on domestic terrorism charges.
Suppose that a green laser shines light with λ = 5.32 × 10−7 m. This light travels outward from the laser through a circular aperture that is 2.50 mm in diameter. How many meters in diameter is the beam, at a jet airliner altitude of exactly 38,000 feet? (Recall that 1 foot = 0.3048 m.)
