Cars are usually fitted with convex side-view mirrors. (i)What is the reason for using of a convex mirror for such purpose? If the focal length of the mirror is -32 cm and the viewed image of a trailing vehicle is reduced in size by a factor of 40, determine: (ii) the distance between the two cars. (iii) The position of the image. (iv) Sketch a ray diagram showing how is the image will be formed.

On the passenger side mirror of cars the statement “Objects in mirror are closer than they appear” is usually printed at the bottom. This is saying that the image viewed by the driver appears to be farther from the mirror than the actual object being viewed is from the mirror. Based on this information, is the mirror flat, concave, or convex? Explain and draw a ray diagram to support your explanation.
