State the mirror equation for spherical mirrors.

State the relation between focal length and radius of curvature for a spherical mirror.

A concave mirror has \(R=0.80\,\mathrm{m}\). Find its focal length.

An object is \(0.60\,\mathrm{m}\) from a concave mirror with \(f=0.20\,\mathrm{m}\). Find the image distance.

For the previous question, find the magnification.

What sign is the focal length of a convex mirror?

An object is \(0.30\,\mathrm{m}\) from a convex mirror with \(f=-0.20\,\mathrm{m}\). Find \(s'\).

For the convex mirror in the previous question, find the magnification.

Where is the image for an object placed at the focal point of a concave mirror?

An object is placed very far from a concave mirror. Where is the image formed?

What does a negative image distance mean for a mirror?

What does negative magnification mean?

A concave mirror has \(f=15\,\mathrm{cm}\). An object is \(10\,\mathrm{cm}\) from the mirror. Find \(s'\).

Find the magnification for the previous question.

Why do convex mirrors give a wider field of view than plane mirrors?

A real image from a concave mirror is projected on a screen. What sign must \(s'\) have?

A concave mirror produces an image twice the object height and inverted. If the object distance is \(30\,\mathrm{cm}\), find the image distance and focal length.

Why are spherical mirror equations limited to paraxial rays?

A concave mirror is used for shaving or makeup. Where should the face be relative to the focal point?

Explain how the signs of \(s'\) and \(m\) classify a spherical mirror image.
