The electric field part of an electromagnetic wave in a medium is represented by
The wave is :
Step 1: Given data:
The electric field part of an electromagnetic wave in a medium is represented by,
Step 2: Formula used:
The standard equation of electromagnetic wave is given by:
Where,
is the Electric field in direction at '‘ distance and ’' time
is the maximum Electric field
is the angular frequency
is the propagation constant
Where, is the wavelength
Where is the frequency
Step 3: Compare with the standard equation:
The given equation of electromagnetic wave is,
Compare this with the standard equation of electromagnetic wave ,
Therefore,
The angular frequency is
The propagation constant is
Step 4: Wavelength
The propagation constant is
So, Where, is the wavelength
That is,
Substituting the value of propagation constant,
Step 5: Frequency
The angular frequency is
So, Where, is the wavelength
Substitute the value of angular frequency,
Thus, the wave is having a frequency of and wavelength is .
