Question

a convex lens of focal length 15 cm is placed in front of a plane mirror a convex lens of focal length 15 cm is placed in front of convex mirror both are coaxial and length is 5 cm from the effect of the mirror when the object is placed on the actual the distance of 20 cm from the length is found that the image coincides with the object calculate the radius of the curvature of the mirror

Answer 1

Answer:

for convex lens: u = - 20cm, f = 15cm 1v - 1u = 1f 1v = 1f + 1u 1v = 115 + (1-20) v = -15 × 20-20+15 = 3005 = 60cm for mirror: u = 55cm, f = ? for the ...
