A narrow slit S transmitting light of wavelength `lamda` is placed a distance d above a large plane mirror as shown in figure. The light coming directly from the slit and that coming after the reflection interference at a screen `sum` placed at a distance LD from the slit. a. What will be the intensity at a poiint just above the mirror. i.e., just above O? b. At what distance from O does the first maximum occur?
