The moon's distance from the earth is ~ 3.84 × 108m. A laser pointer is mounted on a turntable such that its beam repeatedly sweeps over the surface of the moon. If it rotates at a period of 4s, prove that its impact spot travels across the moon at about twice the speed of light. Why does this not violate the law that nothing can travel faster than the speed of light?

Throughout this homework assignment, you may use c to denote the speed of light in both your work and final answers without using its numerical value. (This is actually preferred unless the problem requires the numerical value of c.) 1. The moon's distance from the earth is ~ 3.84 × ǐ0sm. A laser pointer is mounted on a turntable such that its beam repeatedly sweeps over the surface of the moon. If it rotates at a period of 4s, prove...

The distance between the earth and the moon has been very
accurately measured by reflecting laser light off special
reflectors placed by the Apollo manned moon landings (a) A pulse of
laser light is emitted from the earth, reflects off the moon and
returns. If it takes 2.56s to complete this journey what is the
distance from the earth to the moon? (b) The laser is then made to
scan across the surface of the moon creating a spot that...

Problem 9.07 - Enhanced - with Solution 2 of 4 A Review Constants A laser beam aimed from the earth is swept across the face of the moon. For related problem-solving tips and strategies, you may want to view a Video Tutor Solution of Rotation of a compact disc. Part A If the beam is rotated at an angular velocity of 1.50 x 10-rad/s, at what speed does the laser light move across the moon's surface? (See Appendix E in...

Velma's rocket ship is moving away from Mort at a speed of 0.75c. Mort fires a laser beam toward her spaceship, observing the tip of the laser beam to move away from him at speed c. Velma observes this laser beam to move past her at a speed of 1.75c. 1.25c. 0.25c. 0.75c. None of the above. We know that light is quantized because, in the double slit experiment with light, when one slit is closed, no interference pattern shows...

Many communication satellites are placed in a circular orbit around the Earth at a radius where the period (the time to go around the Earth once) is 24 hours. If the satellite is above some point on the equator, it stays above that point as the Earth rotates, so that as viewed from the rotating Earth the satellite appears to be motionless. That is why you see dish antennas pointing at a "fixed" point in space. (a) Calculate the radius...
