3. In the double-slit experiment, suppose the electric fields of the two waves arriving at a point P on the screen is given by Ej = sin(1015t) in µV/m E2 = sin(105t + 24 rad) in µV/m where time t is in seconds. (a) What is the amplitude of the resultant electric field at point P? (b) What is the ratio of the intensity Ip at point P to the intensity Icen at the center of the interference pattern? (c) Describe where point P is in the interference pattern by giving the order of the maximum or minimum on which it lies, or the order of the maximum and minimum between which it lies.
