Interference of Light Interference of Light Intensity of doubleslit pattern Three slits Youngs Double Slit Experiment Youngs Double Slit Experiment Screen at infinity Path difference Minimum intensity at d d sin = ( m + ) , m = 0, 1, 2, x = d sin Maximum intensity at d sin = m , m = 0, 1, 2, x Find the intensity of the doubleslit interference pattern as a function of position on the screen. where: Two waves: E 1 = E sin( t ) E 2 = E sin( t + ) 2 2 sin x d = = 2 2 1 2 4 cos ( ) 2 2 with sin R R I E I x d = = = = Trigonometry: sin a + sin b = 2 cos [(ab)/2] sin [(a+b)/2] E 1 + E 2 = E [sin( t ) + sin( t +...
