Monday Homework Problem $15\mathrm{.}8$ The blue laser in a blue ray DVD player is $405$nm laser in vacuum. The laser strikes a quartz crystal with index of refraction $1\mathrm{.}46$ at normal incidence. The power of the laser is $0\mathrm{.}25$W and I$$m guessing the beam is circular with radius $0\mathrm{.}1$mm$.$ What is the intensity of the light transmitted into the crystal? Select One of the Following: $($a$)7\mathrm{.}7106$ W m$2($b$)1\mathrm{.}5106$ W m$2($c$)6\mathrm{.}5106$ W m$2($d$)2\mathrm{.}85$ W m$2$
