97.29: A student performs an experiment similar to Yonnwq- mu5e,4w ung’s Double Slit Experiment. Coherent light passes through two narrow slits and produces a pattern of alternating bright and dark lines on a screen. Which of the following would cause the bright lines onuem w,-n5 nwq4 the screen to be further apart?
I. Increasing the distance between the slits.
II. Decreasing the distance between the slits.
III. Decreasing the wavelength of the light.
