Copy the intensity-position axes in Figure 3.1 and sketch a graph to show how the intensity varies with position for a monochromatic light (i) source. For an interference pattern to be observed, the light must be emitted by two coherent sources. Explain coherent sources. (ii) (iii) Explain how the use of the single slit in the arrangement above makes the light from the two slits sufficiently coherent for fringes to be observed.

In a double-slit experiment, the third-order maximumfor light of wavelength 480 nm is located 16 mm from thecentral bright spot on a screen 1.6 m from the slits. Light ofwavelength 650 nm is then projected through the sameslits. How far from the central bright spot will the secondorder maximum of this light be located?
A physics professor wants to perform a lecture demonstration of Young’s double-slit experiment for her classusing the 633-nm light from a He–Ne laser. Because thelecture hall is very large, the interference pattern will beprojected on a wall that is 5.0 m from the slits. For easyviewing by all students in the class, the professor wants thedistance between the m=0 and m=1 maxima to be35 cm. What slit separation is required in order to producethe desired interference pattern?

A 5.08-cm-long rectangular glass chamber is inserted into one arm of a Michelson interferometer using a 633-nm light source. This chamber is initially filled with air (n=1.000293) at standard atmospheric pressure but the air is gradually pumped out using a vacuum pump until a near perfect vacuum is achieved. How many fringes are observed moving by during the transition?
