Unformatted text preview: viewed on a screen 3.20 m from the slit. The distance on the screen between the central maximum and the third minimum is 2.5 cm. What is the width of the slit? 5. If the two 2 nd order maxima (m = 2) are separated by 2.0 cm on the screen in a doubleslit experiment, what is the separation of the m = 3 minima? Assume the angle is very small. A. 1.5 cm B. 2.0 cm C. 2.5 cm D. 3.0 cm E. 3.5 cm 6. In a singleslit experiment, light of wavelength 500 nm is used to produce a diffraction pattern on a screen 4.0 m away. If the distance between both 3 rd order minima is 6.0 cm, what is the slit width? A. 2.0 × 104 m B. 1.0 × 104 m C. 4.0 × 104 m D. 0.67 × 104 m E. 0.44 × 104 m 7. When the slit width is doubled, what happens to the width of the central maximum in the diffraction pattern? A. Nothing. B. It doubles. C. It halves. D. It quadruples. E. It quarters....
