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 (532nm) d=1mm d=2 mm Red Laser (680 nm) r-10 m A. Calculate the Intensity of the green laser just after it exits the laser. Express your answer in W/m. B. Calculate the Intensity of the red laser just after it exits the laser. Express your answer in W/m. 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 (10) to the intensity of the laser beam just as it exits the laser (10): 10? a. 1 b. 0.316 c. 0.1 d. 0.00316 e. 0.001
