Question

A spherical concave mirror has a radius R=360 mm forms an image of a h(object)=12 cm high object located d0=p=0.9 m from the vertex of the mirror. Find the position di=q(cm) and the height cm of the image.

Answer 1

1/p + 1/q = 2/R

p = 0.9 m
R = 0.36 m
Solve for q

Image height = h*(q/p)
