Hey there!

Answer:
<B><I>
1). Electromagnetic waves propagate in the form of varying electric field and magnetic fields, such that the two fields are perpendicular to each other and also to the direction of propagation of the wave.


2). Electromagnetic waves are produced by accelerated charges.


3). Electromagnetic waves do not require any material medium for their propagation.


4). In free space, electromagnetic waves travels with a velocity of light.


5). The electromagnetic waves obey the principle of superposition.


6). The electric vector is responsible for optical effects due to an electromagnetic wave. for this reason, electric vector is called light vector.


7). The energy in electromagnetic waves is divided equally between the electricand magnetic field vectors.


8). The energy transported by electromagnetic waves per second per unit area is represented by a vector quantity S, called polynting vector.

9). The intensity of electromagnetic waves i.e energy crossing per second per unit area.
