Ray Optics Question #1: Concave Mirror Image Formation

AI Thread Summary
To locate the image formed by a concave mirror with an object 12 cm in front and a focal length of 21 cm, the mirror equation relating object distance (s), image distance (s'), and focal length (f) can be applied. The standard equation is 1/f = 1/s + 1/s', which helps determine the image distance. The image will be inverted due to the properties of concave mirrors when the object is placed outside the focal point. The discussion emphasizes the importance of consulting the textbook for the equation. Understanding these concepts is crucial for solving similar problems in optics.

There is a standard equation relating the focal length to the object and image distances. It should be in your textbook. It's the same equation that is used for a lens .

Hope that helps get you started.
