Question 3 2 pts Interference microscopes enhance contrast between objects and background by superimposing a reference beam of light and light emerging from a sample, as shown. Object Background material Since light from the background and objects differ in phase, there will be different amounts of constructive and destructive interference, producing the desired contrast in nal intensity. Suppose the sample is a bacillus with a width of 10 micrometers and an index of refraction of 1.45. What kind of interference will occur if light with a wavelength of 600 nm is used to examine the bacillus? Assume that the background material has an index of refraction of 1.0. O Constructive Q Destructive
