Concave and Convex Mirrors

Statement of Purpose
To explore the image formed by both concave and convex mirrors

Procedure

Convex Mirror

 

Nearby image

The image appears at the center of the mirror about the same size, maybe smaller and upright.

Distant Image

At a further distance, the image decreased in size.

 The observations that were made agree with phase diagrams listed here.

Sample calculation

 

 

Convex mirror

Distant image

 The image here is focused at the center of the mirror which appears smaller and inverted.

Nearby Image
 

At a closer distance the image increases in size and is still inverted.

The phase diagram shows that if the object distance decreases and the image distance increases the height of the object will increase, perfectly describing our observation.

Conclusions 
The purpose of the mirrors has been observed. That is why convex mirrors are used in small markets for a lower magnification, hence wider view of the market, whereas concave mirrors are handy for putting on make-up because the higher magnification.
