SPHERICAL MIRRORSMeaningSpherical mirrors are the one which are in shape of piece that have been cut out from aspherical surface. There are two types of spherical mirrors. It can be in the form of concave aswell as convex mirrors (Karttunen and et.al., 2016). The commonly used examples of concavemirrors are shaving and make up mirrors. Convex mirror are in the shape of spoon and hence,common example of it is side mirrors of the car.1
