A.
The surface defined by the locus of points having same phase, is called a wave front |
|
B.
The wave whose surface of constant phase are parallel planes, is known as a plane wave |
|
C.
The relative phase difference between the waves is important and not the absolute phase of a point on the wave |
|
D.
All of these |
|
A.
Topology describes the geometric characteristic of objects which do not change under transformations and are independent of any coordinate system |
|
B.
Topological characteristics of an object are independent of scale measurement |
|
C.
The three elements of topology are adjacency, containment, and connectivity |
|
D.
All of these |
|
A.
When the electric field oscillates in the direction of the electric vector, a plane polarised wave is formed |
|
B.
When the electric vector is in the plane of incidence, vertical polarisation is formed |
|
C.
When the electric vector is at right angles to the plane of incidence, horizontal polarization wave is formed |
|
D.
All of these |
