If you had two repeated disturbances on the surface of a water, I know interference will occur. However, if I move the two sources of disturbances closer together, why would the 'gaps' between each wave increase?

Thanks in advance for your help!

"I move these two disturbances" - Do you mean that you're moving the sources for ripples..? –  Waffle's Crazy Peanut Apr 11 '13 at 16:04
Yes, if the sources of the ripples were moves closer together, I'll change it. Thanks! @CrazyBuddy –  Hummus Apr 11 '13 at 16:05
