(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 A = 5.32 x 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.)

### Safety and Scientific Analysis of Laser Light

#### Safety Warning
Never shine a green laser at anyone, especially not at an airplane, since the pilots can see the beam. Some individual did this in 2002, leading to an arrest on domestic terrorism charges by the F.B.I.

#### Scientific Problem
Suppose a green laser emits light with a wavelength (\(\lambda\)) of \(5.32 \times 10^{-7}\) meters. This light exits through a circular aperture with a diameter of 2.50 mm. We seek to find the diameter, in meters, of the laser beam as it reaches a jet airliner flying at an altitude of exactly 38,000 feet.

*(Note: Remember that 1 foot equals 0.3048 meters.)*
