In the figure, a broad beam of light of wavelength 656 nm is sent directly downward through the top plate of a pair of glass plates. The plates are 120 mm long, touch at the left end, and are separated by 61 pm at the right end. The air between the plates acts as a thin film. How many bright fringes will be seen by an observer looking down through the top plate?

![**Chapter 35, Problem 073**
In the figure, a broad beam of light of wavelength 656 nm is sent directly downward through the top plate of a pair of glass plates. The plates are 120 mm long, touch at the left end, and are separated by 61 µm at the right end. The air between the plates acts as a thin film. How many bright fringes will be seen by an observer looking down through the top plate?
[Figure Explanation: A diagram is shown below the text. The diagram consists of a pair of glass plates. The plates are depicted as touching at the left end and gradually separating towards the right end. Red arrows pointing downward on the left side of the diagram indicate incident light falling on the plates.]
