Question

plz answer this (b) question for more points

Answer 1

$\mathfrak{The\:Answer\:is}$

b) Focal length of the lens, F = 1/ Power of the lens ⇒ F = 1/P ⇒ F = 1/5 ⇒ F = 0.2 m ⇒ F = 20 cm

To get the magnified image the concave lens cannot be used as it forms the dimisnished image only. So we can use a convex lens to do so.

Answer 2

HEYA MATE

HERE IS YOUR ANSWER.

1/F =P (P IS POWER AND F IS.

FOCAL LENGTH) .

1/5=F

F=0.2

✏IT FILL GIVE MAGNIFIED IMMAGE.
