Light from two lasers is incident on an opaque barrier with a single slit of -7 width 4.0 x 10 m. One laser emits light of wavelength 4.0 x 10'm and -5 -7 the other is 6.0 x 10 m. A screen to view the light intensity pattern is 2.0 m behind the barrier. What is the distance from the center of the pattern to the nearest completely dark spot (dark for both colors)? (Enter your answer in cm with one digit after the decimal point. your answer is 17.507 cm, then enter "17.5") -2 1 cm = 10
