A 30.0-W laser emits a beam of light 5.0 mm in diameter. The laser is aimed at the Moon. By the time it reaches the Moon, the beam has spread out to a diameter of 85 km. What was the intensity of the light just as it first exited the laser? (Intensity has units of power per unit area)What is the value of the intensity where it hits the moon? (Assume there is no absorption in the atmosphere on the way)
