Magnification is the measure of how tall the image is in relation to the object. The concave mirrors produce virtual or real, erect or inverted, diminished or the same size depending on the position of the object placed.The expression for magnification is given as, where is the height of the object and is the height of the image. and , can have negative or positive according to the cartesian sign convention.When the image and the object have the same size the magnification will be one.The magnification will be less than one if the image is shrunk.If the image is enlarged the magnification will be greater than one.The negative sign indicates that the image is real and the positive indicates that the image is virtual.A concave mirror has negative magnification. The height of the image divided by the height of the object determines the magnification of the concave mirror. Therefore, if the image is inverted and real then the magnification will be negative.

A science student is riding on a flat car roof train that is traveling at a constant speed of 10 mph on a straight horizontal track. The student throws a ball into the air along a path that he just made to make an initial angle of 60 degrees with the horizontal and to be in line with the track that the student's professor, who is standing nearby, observes the ball rising. How high does the ball rise vertically?
