In Young's double slit experiment, the bright fringes are created because of O constructive interference. O the colour of the viewing screen. O destructive interference. O extra laser beams within the double slits.Question 1 A single slit diffraction pattem is observed on a screen that is 2.00 m from the slit. The slit width is 185 times the incoming wavelength. How wide is the central maximum? {3' 185 m {3' 185 m {3' 0.00541 m (:3 0.021 Er I'n Question 2 A swimmer underwater is able to see the sun at 50.0\" above the horizontal.
