an object 1 cm high produces a real image 1.5 CM when placed at a distance of 15 cm from a concave mirror calculate the position of the image and the magnification |

Answer» high H1 = 1cmImage HEIGHT H2 = 1.5cmObject DISTANCE u = -15cm (OBJECT is taken behind the mirror)SINCE, magnification = image height/object height,M = H2/H1 = 1.5/1 = 1.5Since, also, magnification = image distance/ object distance=> 1.5 = image distance/-15=> image distance = -22.5cm=>22.5 cm behind the mirror |
