ACL Stage Left - David Garza - Disco Ball World
The Mystic Bright Fringes, the hippie disco band, is holding its thirty-year reunion concert at the Hollywood?
The Mystic Bright Fringes, the hippie disco band, is holding its thirty-year reunion concert at the Hollywood Bowl. The show opens with the stage dark except for a giant rotating mirrored disco ball, 2.43 m in diameter, illuminated by a laser beam shining through a pinhole aperture from the far back of the open amphitheater, 325 m away. The laser uses light of wavelength 671 nm and has an adjustable aperture. What should the diameter of the laser aperture be so that the central bright spot of the laser's diffraction pattern just covers the disco ball?
Please Help!
First, you need to find theta. so use arc sin(2.43/325)
Once you have your angle use sin (.4284)= 1.22(671e^-9/d)
divide by 1.22 on both sides. .00613=(671e^-9/d)
Divide by the wave length 9135.62=(1/d)
Solve for d. 1.09e-4=d
This is the tricky part. The aperture needs to twice as large because this will only cover half of the ball.
2.19e-4 should be your answer.
Took all of my subs to get that one.
The group is also eager to extend this principle to tax funding of religion. In other words, if an arm of the government is funding a secular activity, its failure to also direct tax support to a “faith-based” equivalent would be seen as a form of discrimination.
That works. There's no way they could fund Christian “faith-based” efforts and not give the same level of support to Scientology, the FSM or the Church of Mouse and Disco Ball efforts. One lawsuit would ensure that the First Church of Bob was entitled to suck off the government teat just as hard as the Baptists.
