Double slit In a double slit experiment, two very narrow slits, which are separated by 0.03 mm, are illuminated by 600 nm light. The interference pattern is observed three times on three different screens, each one placed 12 m from the slits. Hints: 1. For this problem, I find it easier to think in terms of the angle Om of the m" interference maximum rather than its position I'm on the screen. 2. Remember that in order to use the small-angle approximation you must have (roughly) 0
