1. Thomas Young wishes to measure very small distances using the interference pattern generated by monochromatic light. The pattern must be widely spaced with numerous fringes and clearly dened. Which of the following experimental set-ups would generate the most suitable pattern? a. red light and narrow double slits spaced close together b. red light and a narrow single slit c. blue light and narrow double slits spaced close together d. blue light and a wide single slit A Light from a monochromatic source shines on a single slit. Which diagram best illustrates the interference pattern observed on the screen? (a) I I I I I I I I I (b) I I I I I I I I III III\" (dlll I I ll (all
