You set up Young's double slit experiment by making two slits d = 1.2 mm apart and the screen is placed D = 1.2 m away. M =+1 What is the separation Ay between two bright fringes when a. d blue-green light of wavelength A = 600 nm falls on the slits? D b. What will happen to that separation in each of the following conditions. Explain with numbers if necessary: 1. The screen is moved away from the plane of the slits. 2. The ( monochromatic) source is replaced by another (monochromatic) source of shorter wavelength. 3. The separation between the two slits is increased. 4. The monochromatic source is replaced by a source of white light
