waves - Double-Slit Experiment Separation Between Fringes



I was taught in class that the double slit diffraction pattern would always have bright fringes of same length. We derived the formula: $y=m(\lambda)(L)/d$, which also shows this equal distance. I look at these pictures now, and I see a central maximum with almost twice the largeness of other fringes. What is going on?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
