FIGURE P33.56 shows the light intensity on a screen behind a single slit. The wavelength of the light is and the slit width is . What is the distance from the slit to the screen?
The distance from the slit to the screen
Remember that the entire width of a main fringes in the single study is given by
In an intellectual result, we can resolve parametrically only for the length to find a solution.
In terms of quantity, our length will just be
A Michelson interferometer is set up to display constructive interference (a bright central spot in the fringe pattern of Figure) using light of wavelength l. If the wavelength is changed to , does the central spot remain bright, does the central spot become dark, or do the fringes disappear? Explain. Assume the fringes are viewed by a detector sensitive to both wavelengths.
