    If the cut part of the glass sphere is coated from inside with silver or a similar material, then its outer surface reflects the entire light incident on it, and thus forms a mirror. Since the outer surface is a convex surface, the mirror so formed is called a convex mirror. Convex mirror is used in rear view mirrors, as it shows smaller images from a bigger field of view.

    Heart is the central organ for pumping the blood throughoutt he body. It is located in the chest cavity with its lower part pointing towards the left. Its size is that of the person’s fist. 

    •  It pumps blood rich in carbon dioxide to the lungs and oxygen-rich blood to other parts of the body. 
    •  The heart consists of four chambers namely atria and ventricles. The two upper chambers of the heart are known as the atria. The two lower chambers of the heart are the ventricles.
    •  The deoxygenated blood is completely separated from the oxygenated blood completely. The atria and ventricles are separated by many types of valves which prevent the mixing up of pure blood from that of impure blood. 
    •  Heart is made up of strong cardiac muscles. The rhythmic contraction and relaxation of the heart constitutes heartbeat.
    •  Heartbeat can be recognized by placing the palm on the left side of the chest. Stethoscope is a device that amplifies the sound of your heartbeat.
    •  The pressure applied by blood on the walls of an artery at a particular part is the pulse. The number of times the heart beats in a minute is the same as the pulse rate.The ideal pulse rate is 70 to 80 per minute.

    Fig.  (a) A triangular glass prism and (b) its principal section


    The two plane faces ABED and ACFD inclined to each other are called refracting faces of the prism.

    The line AD along which the two refracting faces meet is called refracting edge of the prism.
    The face BCFE opposite to the refracting edge is called base of the prism.
    The angle A at which the two refracting faces are inclined to each other is called Angle of the prism.

    A section ABC made by a plane, at right angle to the refracting edge is called principal section of the prism.
