A mixture of one mole each of ${\mathrm{H}}_2,\mathrm{H}\mathrm{e}$  and ${\mathrm{O}}_2$ each are enclosed in a cylinder of volume $V$  at temperature $T$ . If the partial pressure of ${\mathrm{H}}_2$  is $2\mathrm{a}\mathrm{t}\mathrm{m}$ , the total pressure of the gases in the cylinder is:

To measure light intensity we use
