FREE-BODY DIAGRAM

Image
Free-body diagrams are diagrams that are used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A diagram which shows a part of a system separately, indicating all the external forces acting on it ,is called as a free body diagram. These diagrams will be used throughout our study of physics. A free body diagram is a special example of the vector diagrams. In case of a free body diagram , a body is said to be "free" when it is singled out from other bodies for the purpose of dynamic or static study or analysis.

Transverse nature of Electromagnetic Waves

Image
Electromagnetic waves are transverse in nature.Electromagnetic waves consist of an electric vector (E)  and a magnetic vector (B) mutually perpendicular to each other and they are also perpendicular to the direction of propagation of the wave. The electric vector (E) ,magnetic vector (B) and the propagation vector (K) form a right handed set (all the three mutually perpendicular to each other).
