Problem $8.($Laser Pointers$)$ Here we compare two lasers pointers. The green laser emits $1$ mW of light power in a beam that is $1$ mm in diameter. A red laser emits $2$ mW of power in a beam that is $2$ mm in diameter. Green Laser $(532$ nm$)$ d $=1$ mm Red Laser $(680$ nm$)$ d $=2$ mm $\text{'}$ r $=10$ m A$.$ Calculate the Intensity of the green laser just after it exits the laser. Express your answer in W$/$m$2$ B$.$ Calculate the Intensity of the red laser just after it exits the laser. Express your answer in W$/$m$2$ C$.$ Which laser has the greater power a$.$ Green b$.$ Red D$.$ Assuming the green laser beam is collimated $($does not spread with distance$),$ what is the ratio of the intensity of the laser beam after it has traveled $10$ meters $(110)$ to the intensity of the laser beam just as it exits the laser $($l$)$: $-10?$ a$.1$ b$.0\mathrm{.}316$ C$.0\mathrm{.}1$ d$.0\mathrm{.}00316$ e$.0\mathrm{.}001$
