Question

The distance between a real object and its real image is 56 cm formed by converging lens, focal length of lens is (A) f ≤ 14 (B) f >14 (C) f=14 (D) f=28

Tardigrade Admin · Accepted Answer

f ≤ (D/4) f ≤ (56/4) f ≤ 14 cm

Q. The distance between a real object and its real image is $56 c m$ formed by converging lens, focal length of lens is

$f \leq 14$

$f > 14$

$f = 14$

$f = 28$

$f \leq \frac{D}{4}$
$f \leq \frac{56}{4}$
$f \leq 14 c m$

f≤14

f>14

f=14

f=28
