Question

How do you calculate maximum and minimum focal length of eye lens​

Answer 1

Answer:

don't know the answer bro but need points urgently please forgive me

Answer 2

Answer:

The minimum focal length of eye lens is 2.27 cm.

• The distance between lens and retina is 2.5cm.
• Image is formed at retina.
• Hence, image distance for eye lens(v) = 2.5cm.

Maximum focal length:

• For maximum focal length, object is at infinity.
• Hence, in this case u = - ∞, v = 2.5 cm, = ?
• Substituting above values in (1)
