| Answer» TION:Given Two trees are 2 m apart. A person sees them from a DISTANCE of 2 km. Will he see the trees resolved? We need to find whether trees are resolved. The POWER of an optical device to identify near by or adjacent images is RESOLVING power. So d/D > = resolution power of eye So d/D = 2/2 x 10^3 = 2 / 2 x 10^-3 = 0.001 Now resolving power = 1 / 60 degree = 1/60 x π/ 180 rad = 3.14 / 10,800 = 0.0002907 Now 0.001 > 0.00029 So d/D > resolution power of eye Therefore the trees appear resolved.
