Mirror Equation

The Mirror Equation (Concave Mirrors)

Mirror equation example problems | Geometric optics | Physics | Khan Academy

si = 7.5cm; Real; Inverted, 2cm

si = 15cm; Real; Inverted, 4cm

si = 0.13 cm; Real; Inverted, 0.0087cm

si = -7.5cm; Real; Inverted, -2cm

A 4 cm tall object is placed in 15 cm front of a concave mirror with a focal length of 5 cm. Where is the image produced? Is this image real or virtual? Is it upright or inverted? What is the height of the image?

Spherical Mirrors & The Mirror Equation - Geometric Optics

You want to produce a mirror that can produce an upright image that would be twice as tall as the object when placed 5 cm in front of it. What shape should this mirror be? What radius of curvature should the mirror have?
