Wrequide cavmes are commonty constructed using aluminum $(e=3\mathrm{.}54{10}^7(\frac{S}{m})).$ In principle, a higher cavity Q factor could be achieved using a metal with higher conductivity such as selver $)=(6\mathrm{.}17{10}^7(\frac{S}{m}),$ Determine how much higher the Q would be if an aluminum cavity were replaced by a silver carty. Assume all the dimensions $($and hence the resonant, trequency$)$ are loentical for both cavities. Express your answer as the rutio of the Q of the silver cavity to the O of the aluminum cavity to two places after the decimal.
