Question

Using multiple laser beams, physicists have been able to cool and trap sodium atoms in a small region. In one experiment the temperature of the atoms was reduced to $0.240 \mathrm{mK}$ (a) Determine the rms speed of the sodium atoms at this temperature. The atoms can be trapped for about $1.00 \mathrm{s}$ The trap has a linear dimension of roughly $1.00 \mathrm{cm} .$ (b) Approximately how long would it take an atom to wander out of the trap region if there were no trapping action?

Step 1

Given: $T = 0.240 \, \text{mK} = 0.240 \times 10^{-3} \, \text{K}$ $k = 1.38 \times 10^{-23} \, \text{J/K}$ $m = 23 \times 1.66 \times 10^{-27} \, \text{kg}$ Plugging in the values: $v_{\text{rms}} = \sqrt{\frac{3 \times 1.38 \times 10^{-23} \times 0.240 \times Show more…
