Question

4 The green interference fringes (bright spots) shown in the picture on the right are produced on a screen by putting a green laser beam with a wavelength of 550 nm through two identical slits. The scale of the distance along the screen is shown at the top of the figure. S28 d sin e mA sin m-1, y-3cm A. A student group decides that if they know the screen is 4m from the slits they can determine the spacing between the slits. Evaluate the group's solution below, identify the error(s) they made and fix it. (7 pts) .03m 550nm-d05m 4m 73,333nm-d If electrons instead of light were sent through two slits, would they be able to produce an interference pattern like light? (2 pts) B.
