In a TEM wave, both the E and H vectors are perpendicular to the direction of power flow, represented by 'S', the Poynting vector, which in turn is simply the direction in which the wave is travelling.
So neither has any component in the direction of propagation.
But are E and H necessarily perpendicular to one another?
Ex.: P = Pz ẑ
E = Ex x + Ey ŷ
H = Hx x + Hy ŷ

Why TEM modes does not exist in wave guides?
Arif Ullah khan utman kheel this is because for conductor E parallel is zero this means that the surface of the wave guide is at equipotential and this potential follow the laplace equation .it means that there is no maxima and minima inside the wave guide . this means that the electric field inside zero . hence the TEM do not exist in wave guide only TE and TM can be exist . if we place some conductor in the wave guide then the conductor inside will not be equipotential and the TEM waves can be exist . like in Coaxial cables
What is the explanation for the principles of electromagnetic wave?
An electromagnetic wave is properly called a Transverse Electro Magnetic wave, or TEM wave. It consists of an alternating magnetic wave at right angles to an alternating electric wave, with both fields being at right angles to the direction of propagation. The plane of the electric field is defined as the plane of polarization.
What is the formula for wave speed?
There are a few different formulas, depending on what measurements you know. For mechanical waves . . . the mechanical characteristics of the medium. For electromagnetic waves . . . the electrical characteristics of the medium. For all waves . . . the product of (wavelength) multiplied by (frequency).
Compare the process used to produce a TEM and an SEM?
The process used to produce TEM will cut cells and tissues in to ultra-thin slices so that they can be viewed under the microscope. However, the ones on SEM do not need to be cut as they can easily be visualized.
What is the different between half wave and full wave?
As states half wave will rectify only either positive or negative of a full wave. full wave will rectify positive and negative making it full wave rectification.

Why TEM wave cannot propagate thorough a rectangular waveguide?
TEM modes (Transverse ElectroMagnetic) have no electric nor magnetic field in the direction of propagation. In hollow waveguides (single conductor), TEM waves are not possible, since Maxwell's Equations will give that the electric field must then have zero divergence and zero curl and be equal to zero at boundaries, resulting in a zero field.

Why TEM waves cannot propagate in a wavwguide?
In a waveguide, transverse electromagnetic (TEM) waves cannot propagate because they require both electric and magnetic field components to be present and perpendicular to the direction of propagation. In a waveguide, the fields are constrained to be transverse to the direction of propagation, which is not possible for a pure TEM wave.
What are four characteristics of a wave that can change?
Four characteristics of a wave that can change are amplitude (height of the wave), frequency (number of wave cycles per unit time), wavelength (distance between wave crests), and speed of propagation.
What are the characteristics of sound waves?
The characteristics of a sound wave is the Amplitude, Frequency, Wavelength, time period, and velocity. The sound wave itself is a longitudinal wave that shows the rarefactions and compressions of a sound wave.
Which type of wave has both transverse and longitudinal characteristics?
Earthquake wave.
Why the both electric and magnetic field are don't exist in the direction of wave propagation in tem waves?
In TEM (transverse electromagnetic) waves, the electric and magnetic fields are perpendicular to each other and perpendicular to the direction of wave propagation. This is because the wave is designed to have components that oscillate in orthogonal planes, allowing the wave to propagate without the need for a medium to carry it.
Which wave cannot exist inside wave guide?
TEM TE modes (Transverse Electric) have no electric field in the direction of propagation. * TM modes (Transverse Magnetic) have no magnetic field in the direction of propagation. * TEM modes (Transverse ElectroMagnetic) have no electric nor magnetic field in the direction of propagation. * Hybrid modes are those which have both electric and magnetic field components in the direction of propagation
Is light a wave, and if so, what are the properties and characteristics that define it as such?
Yes, light is a wave. It exhibits properties such as interference, diffraction, and polarization, which are characteristics of wave behavior. These properties help define light as a wave phenomenon.

Of the following characteristics of a wave the one that is independent of the others is it?
The frequency of a wave is independent of its amplitude, wavelength, and speed. Frequency refers to the number of complete oscillations a wave undergoes in a given time period and is determined by the source of the wave. It does not affect the other characteristics of the wave.
