A double-slit pattern is obtained using monochromatic light. Consider the following five possible changes in conditions: 1.) decrease the wavelength 2.) increase the wavelength 3.) increase the width of each slit 4.) increase the separation between the slits 5.) decrease the separation between the slits Which of the above would increase the spacing of the interference fringes? 3 only 5 only 2 and 5 only 1 and 5 only 1 and 3 only
