Question

power of lens is -2 diopter find the radius of curvature​

Answer 1

Given :-

Power = -2D

Focal length = 100/-2 = -50 CM

Radius of curvature = 2f = 2* -50 = -100 cm

Answer 2

given :

power of lens = to -2D.

to find :

radius of the curvature.

solution :

w.k.t p =1/f.

f=1/p.

f=1/-2

f=-0.5m.

f=-50cm.

Radius of curvature(r) =2f.

R=2(-50).

R=-100cm..

here is your answer please make my answer is a brain list
