Concave Mirrors
This is a photo of a concave mirror. A concave mirror is a mirror that curves inwards. Concave mirrors are also called converging mirrors. Concave mirrors have Parallel incident rays that reflect through a specific location, called the focal point. Objects reflected off of concave mirrors can be found in 2 different ways. The first way is though a ray diagram. One can draw the different rays going from an object to the mirror and off of the mirror to the point where they intersect and the image of the object will appear. The other was to find the location of the object on a concave mirror is though using the equations 1/f = 1/do + 1/di, followed by the equation m = hi/ho = -di/do. In everyday life, concave mirrors can be found in the headlights of cars because they focus the light rays. Concave mirrors can also be found in bathrooms as "shaving mirrors" because they magnify the image to help whomever is shaving to see what they are doing.
