High-power lasers are used to compress a plasma (a gas of charged particles) by radiation pressure. a laser generating radiation pulses with peak power 2.5 ✕ 103 mw is focused onto 1.0 mm2 of high-electron-density plasma. find the pressure exerted on the plasma if the plasma reflects all the light beams directly back along their paths.
