10. [-/3 Points] DETAILS SERCP11 24.2.P.003. MY NOTES ASK Light at 543 nm from a helium-neon laser shines on a pair of parallel slits separated by 1.53 x 1073 m and an interference pattern is observed on a screen 1.65 m from the plane of the slits. HINT (a) Find the angle (in degrees) from the central maximum to the first bright fringe. (b) At what angle (in degrees) from the central maximum does the second dark fringe appear? (c) Find the distance (in m) from the central maximum to the first bright fringe. m11. [-/1 Points] DETAILS SERCP11 24.2.P.013.MI. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHE Radio waves from a star, of wavelength 274 m, reach a radio telescope by two separate paths, as shown in the figure below (not drawn to scale). One is a direct path to the receiver, which is situated on the edge of a cliff by the ocean. The second is by reflection off the water. The first minimum of destructive interference occurs when the star is @ = 30.0 above the horizon. Find the height of the cliff. (Assume no phase change on reflection. The image is not drawn to scale; assume that the height of the radio telescope is negligible compare to the height of the cliff.) m Direct Radio path telescope Reflected path12. [-/2 Points] DETAILS SERCP11 24.7.OP.031. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A technician directs monochromatic light toward a single slit in an opaque barrier. The light has a wavelength of 500 nm and the slit is 0.170 mm wide. The light that passes through the slit creates a diffraction pattern on a screen, which is 1.60 m from the slit. (a) How wide (in mm) is the central maximum (the central, bright fringe), as measured on the screen? mm (b) How wide (in mm) is either of the two first-order bright fringes, as measured on the screen? mm Need Help?
