Simulation of image formation in concave and convex mirrors. Finding v value for different u values of concave mirror. Characteristics Of An Image From A Spherical Mirror Class 10 Physics Classroom Solutions Lab Activities Physics Image distance v can be both positive and negative for convex lens and concave mirror depending on the position of the object. . MetreBridge-Law of Combination of resistors. A concave mirror can form different image characteristics depending on the position of the object. We wish to describe the characteristics of the image for any given object location. Characteristics of Concave Mirrors. Characteristics of common emitter of npn or pnp transistor. There is a definite relationship between the image characteristics and the location where an object is placed in front of a concave mirror. When the concave mirror is placed very close to the object a magnified erect and virtual image
