l: Question 6 (1 point} Retake question (DIFF:S)_A Ti-Saphire laser delivers a 10 ps pulse of 5 MW average power. If the photons have a wavelength of 600 nm, how many are contained in the pulse? State your answer as a multiple of 1012 to the nearest thousandth of a unit. (Example: 7.89?84x1013= ?B.9?84 x1012 and so the answer would be ?8.9?B). Even though it is a short problem you need to provide brief explanation of your work so o in addition to entering your final numerical answer into the box, solve this problem in detail on paper. Make sure that you write your solution neatly, starting with the clear diagram and all variables on it
