Question

Find the radii of curvature of convexo-concave convergent lens made of glass with refractive index n=1.5 having foval length of 24 cm.one of radii of curvature is double than other

Answer 1

Explanation:

1/f= (n-1) (1/R1-1/R2)

f= -24

R1= R2,n= 1.5

1/-24= (1.5-1)(1/2R2-1/R2)

1/-12= -1/2R2

R2= 6 cm,R1= 12 cm
