In a double-slit experiment, light with a wavelength λ passes through a double-slit and forms an interference pattern on the screen at a distance L from the slits. What statement is true for the resulting interference pattern if the frequency of the light increases? The distance between maxima increases. Not enough information given. The distance between maxima stays the same. The distance between maxima decreases.
