In figure S is a monochromatic point source emitting light of wavelength lambda=500 nm . A thin lens of circular shape and focal length 0.10 m is cut into two identical halves L_(1) and L_(2) by a plane passing through a diameter. The two halves are placed symmetrically about the central axis SO with a gap of 0.5 mm . The distance along the axis from S to L_(1) and L_(2) is 0.15 m , while that from L_(1) and L_(2) to O is 1.30 m . The screen at O is normal to SO . (a) If the 3^(rd) intensity maximum occurs at point P on screen, find distance OP . (b) If the gap between L_(1) and L_(2) is reduced from its original value of 0.5 mm , will the distance OP increases, decreases or remain the same?
