Regents Physics Date. Homework # 14- Interference of Light Handout Problems: 1. An interference pattern is produced on screen B when light passes through the double slit in A. Compared with the value of distance x for yellow light, will the value of x for blue light be less, greater or the same. Explain. A First-order bright line X Central maximum -L =5.0 m Barrier Screen 2. If the distance between the slits in the diagram above is decreased, what will happen to the distance between the central maximum and the first order bright line? Explain. 3. Show in a diagram the arrangement of the different colors of light in a typical bright band formed by a double slit when white light is passed through the slits." 4. Monochromatic light passes through two slits 0.030 cm apart and falls on a screen 120 cm away. The first-order bright band is 0.16 em from the middle of the center band. What is the wavelength of the light? 5. Yellow light of wavelength 6.0 x 10" cm passes through two narrow slits 0.020 em apart and forms an interference pattern on a screen 180 cm away. How far apart are the central bright band and the first- order bright band
