A friend asked me a question on how feasible it would be to use\u00a0gamma rays as an energy source. So let’s crunch some numbers: The wavelength of gamma rays is
\n\\[\\lambda=\\frac{c}{f}=0.005 nm\\]
\nSince the optimum length l for an antenna is
\n\\[l=\\frac{\\lambda}{4}=0.00125 nm=1.25 pm\\]
\nWe are a bit in trouble here since the radius of the atom Sodium for instance is approximately 160 pm.
\nPhysically it’s just not possible to build such a small antenna.<\/p>\n","protected":false},"excerpt":{"rendered":"
