ANSWER:Solution 85GP
Step 1 of 3
(a)
Here we need to find the refractive power of the human eyes when the person is observing rare species of bird in a distant tree with unaided eyes.
In the given problem,we have to treat the eye as a single lens system with the retina which is at from the lens. For the given case, the distance of focus value of
will be infinity.
