Researchers recently reported the first optical atomic trap.In this device, beams of laser light replace the physical wallsof conventional containers. The laser beams are tightlyfocused. They briefly (for 0.5 s) exert enough pressure toconfine 500 sodium atoms in a volume of 1.0 × 10-15 m3.The temperature of this gas is 0.00024 K, the lowest temperature ever reached for a gas. Compute the root-meansquare speed of the atoms in this confinement.
