(4) None of these

Answer 1

Explanation:

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.
