Meters like ammeters and voltmeters use a mirror to avoid parallax error. The reading is taken from a position such that the image of the pointer is directly under the pointer.
The wing and rear-view mirrors of a car are made of a convex and a plane mirror respectively. The two wing mirrors enable the driver to see objects on both sides of the car. The rear-view mirror enables the driver to see things behind the car.
A microscope uses a mirror to reflect light to the specimen under the microscope.
An astronomical reflecting telescope uses a large parabolic mirror to gather dim light from distant stars. A plane mirror is used to reflect the image to the eyepiece.
Parabolic mirrors are used in torches and car headlamps as reflectors. A small lamp is placed at the focus point of the mirror to produce parallel rays.
Concave mirrors with long focal length can be used as shaving mirrors or make-up mirrors as they form magnified and upright images.
Concave mirrors are also used by dentists to examine the teeth of a patient. The concave mirror forms a magnified image of the teeth.
A convex mirror has a wider view than a plane mirror. Therefore, convex mirrors are used as driving mirrors and as shop security mirrors.
Convex mirrors are also used as blind corner mirrors on the road to help drivers view traffic around sharp corners.
An overhead projector as in figure uses a concave mirror to reflect light from the object to the screen.
