Question
Researchers recently reported the first optical atomic trap.
In this device, beams of laser light replace the physical walls
of conventional containers. The laser beams are tightly
focused. They briefly (for 0.5 s) exert enough pressure to
confine 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.
