97.29: A student performs an experiment similar to Young’s Double Slit E9ggl :ft5l/ls xperiment. Coherent light passes through two narrow slits and produces a pattern of alternating bright and dark l:9lfgl5t /g slines on a screen. Which of the following would cause the bright lines on 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.
