Aphysics professor wants to perform a lecture demonstration of young's double-slit experiment for her class using the 633-nm light from a he-ne laser. because the lecture hall is very large, the interference pattern will be projected on a wall that is 7.0 m from the slits. for easy viewing by all students in the class, the professor wants the distance between the m=0 and m=1 maxima to be 35 cm. what slit separation is required in order to produce the desired interference pattern?
