Question

D) More information needed. 3. Monochromatic light falling on two slits 0.5 mm apart produces the second order fringe at 0.15 angle. The interference pattern from the slits is projected onto a screen that is 3.00 m away (a) What is the wavelength of the light used (in nm)? (b) What is the separation distance (in mm) on the screen of the second bright fringe from the central bright fringe? (c) What is the separation distance on the screen of the second dark fringe from the central bright fringe? A red laser shines on a pair of slits separated by a distance d, producing an interference p green laser of the same intensity is then used to illuminate the same slit pair. Compared to the red laser, the green laser will produce an interference pattern with maxima that are A) in the same locations. B) brighter C) farther apart. D) dimmer. 4. E) closer together 5. Conducting an experiment with a 532-nm wavelength green laser, a researcher notices a slight shift in the image generated and suspects the laser is unstable and switching between two closely spaced wavelengths, a phenomenon known as mode-hopping To determine if this is true, she decides to shine the laser on a double-slit apparatus and look for changes in the pattern. Measuring to the first bright fringe on a screen 0.5 m away, with a slit separation of 80 μm' she measures a distance of 3.325 mm. When the laser shifts, so does the pattern and she then measures the same fringe spacing to be 3.375 mm. (a) What wavelength is the laser "hopping" to? (b) Draw a diagram indicating the location of the bright fringes for the above wavelengths.
