Question

A concave mirror (f₁ = 14.4 cm) and a convex mirror (f₂ = ?5.80 cm) are facing each other and are separated by a distance of 36.0 cm. An object is placed between the mirrors and is 18 cm from each mirror. Consider the light from the object that reflects first from the concave mirror and then from the convex mirror. What is the distance of the image (d_i2) produced by the convex mirror?.

Answer 1

1/do1 + 1/di1 = 1/f1

(1/18) + (1/d1i) = (1/14.4)

d1i = 72 cm

for convex mirror

d2o = -36 cm

1/d2o + 1/d2i = 1/f2

-(1/36) + (1/d2i) = (-(1/5.8))

d2i = -6.91 cm <_------------answer
