In the double-slit experiment, suppose the electric fields of the two waves arriving at a point P on the screen is given by
E1 = sin((10^15)t) in μV/m
E2 = sin((10^15)t + 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.
