The electromagnetic waves can be characterised by the parameters like wavelength, frequency, phase and state of polarization.
Wavelength :
The distance between two-crust or two throughs is known as wavelength.
Wavelength denoted by λ.
Frequency :
Frequency is the quantity that represents a number of oscillations that particle carries out in unit time.
Frequency denoted by ν.
Wavelength (λ) = c / Frequency (ν)
Where c = velocity of electromagnetic wave
Phase difference :

Frequency :
Frequency is the quantity that represents a number of oscillations that particle carries out in unit time.
Frequency denoted by ν.
Wavelength (λ) = c / Frequency (ν)
Where c = velocity of electromagnetic wave
Wavelength × Frequency = Velocity of the wave
The wavelength of the electromagnetic wave varies from 10-12 meters to 104 meters.
Phase :
The electromagnetic wave can be represented by a sine or cosine function.
E = E0 Sin (wt + Φ )
Where E = Position of a wave at time t
E0 = Maximum displacement of
Amplitude
(wt + Φ ) = Phase of the wave
Φ = Initial phase or phase difference
Phase difference :
The difference between the phase if the two waves or phase of two position of a single wave is known as phase difference.
