WebWith a beam divergence of 1 mRad, the laser will have a beam width of 10 m over 10 km. It means the observer at 10 km away in the middle of the beam can change their height by 5 m and still be able to see the direct laser beam. Lasers are just a form of light. WebIn conditions that produce superior mirages, there are inversion layers in which the ray curvature exceeds that of the Earth. Then, in principle, you might see infinitely far — there really would be no horizon — assuming that the thermal inversion extended to the top of the atmosphere. To an observer within such a super-refracting inversion ... WebIn practice, to find , one must be using a value of 8.5·10 3 km for the effective Earth's radius (4/3 of it), instead of the real one.
