Explanation:Electromagnetic wave propagation characteristics are fundamental in various fields, including telecommunications, radio frequency engineering, and radar systems. The calculator helps you understand key parameters like wave velocity, refractive index, and phase velocity, which influence signal behavior in different media. The results are based on the input values, such as frequency, wavelength, and speed.

Formula Explanation: 
1. Wavelength (λ):
﻿
λ=fv​λ= fv​λ=fv​
The wavelength represents the distance between two successive points in a wave where the wave is in the same phase. It is inversely proportional to the frequency and directly proportional to the wave velocity. This parameter is important in understanding wave behavior and interactions with different materials.
﻿
2. Wave Number (k):
 
﻿
k=2π​/λ k= 2π​/λ\ k=2π​/λ 
The wave number is the spatial frequency of the wave, specified in radians per unit distance. It is calculated as 2π divided by the wavelength λ. The wave number is a fundamental parameter used in wave propagation analysis and calculations.
﻿
3. Angular Frequency (ω):
﻿
ω=2πfω=2πfω=2πf
The angular frequency, also known as angular speed, is a measure of the rate of rotation of a wave. It is calculated as 2π times the frequency f. Angular frequency is an essential parameter in wave theory and wave behavior analysis.
﻿
4. Intrinsic Impedance (η):
﻿
η=√(μ/ε)​ η = √(μ/ε)​ η=√(μ/ε)​
The intrinsic impedance, also known as the characteristic impedance, of an electromagnetic wave is the ratio of the amplitudes of the electric and magnetic fields. For free space, it can be calculated as the square root of the ratio of the permeability of free space μ to the permittivity of free space ε .It characterizes the ability of a medium to transmit electromagnetic waves.
﻿
5. Wave Velocity (v):
﻿
v=1/√μεv=1/√μεv=1/√με
The wave velocity represents the speed at which the wavefront moves through the medium. It is calculated as the reciprocal of the square root of the product of the permeability of free space μ and the permittivity of free space ε. Wave velocity is a crucial parameter for understanding wave propagation in different mediums.
﻿
6. Phase Velocity (v):
﻿
v=kω​v= kω​v=kω​
 The phase velocity is the velocity at which the phase of the wave propagates. It is calculated as the ratio of the angular frequency (w) to the wave number (k). Phase velocity is important in understanding how wavefronts move through space.
﻿
7. Refractive Index (n):
﻿
n=c/vn=c/vn=c/v
The refractive index is a measure of how much the speed of the wave is reduced when it enters a medium. It can be calculated as the ratio of the speed of light in a vacuum (c) to the wave velocity (v). The refractive index characterizes the behavior of electromagnetic waves as they transition between different materials.
