Question number 20. Show all work clearly please. thank you. :)

An object 2.0 cm high is placed 45 cm from a concave mirror of radius 10 cm and radius of curvature 60 cm. Find the location, size, and orientation of the image. Solve both by calculation and by drawing principal rays. An object 2.0 cm high is placed 10 cm from the surface of a polished silver sphere of radius 10 cm. Find the location, size, and orientation of the image. Solve both by calculation and by drawing principal rays. A concave spherical mirror with a focal length of 10 cm faces a plane mirror with the optical axis of the spherical mirror perpendicular to the plane mirror. A small object is placed at point P on the optical axis,

Explanation / Answer

1/s + 1/s' = 2/R

1/9 + 1/s' = 2/(-11)

s' = -99/29 cm (virtual image)

h' = (s'/s)h = (-99/29)(2.2)/9 = -0.834 cm (it's not inverted)
