An object 0720 cm tall is placed 185 cm to the left of the v

An object 0.720 cm tall is placed 18.5 cm to the left of the vertex of a concave spherical mirror having a radius of curvature of 23.0 cm .

Part A

Calculate the position of the image.

Part B

Calculate the size of the image.

Part C

Find the orientation (erect or inverted) and the nature (real or virtual) of the image.

using mirror equation

1/v + 1/u = 1/f

V = 1/(-1/11.5 + 1/18.5) = -30.39 cm

B) size of image = 0.720*V/u = 0.720*-30.39/-18.5 = 1.18 cm

C) image is erect
