1.	A concave mirror of radius of curvature 10 cm is cut into two equal parts, slightly separated and placed in front of a monochromatic line source S of wavelength 2000 ^A as shown in figure. Consider only interference in reflected light after first reflection from mirrors. Assume direct light from S is blocked from reaching the screen If half of reflecting surface of upper part of mirror is painted black then choose correct option
Answer» A concave mirror of radius of curvature 10 cm is cut into two equal parts, slightly separated and placed in front of a monochromatic line source S of wavelength 2000 $^A$ as shown in figure. Consider only interference in reflected light after first reflection from mirrors. Assume direct light from S is blocked from reaching the screen If half of reflecting surface of upper part of mirror is painted black then choose correct option
