Question

The wavelength of a wave with propagation constant (0.1π + j 0.2π) m-1 is

Answer 1

we know,
Propagation constant = α + jβ
where α is attenuation constant
β is phase constant.
we know , phase constant = β = 2π/λ , here λ is wavelength

Now, propagation constant =( 0.1π + j 0.2π )m⁻¹
β = 0.2π
2π/λ = 0.2π
λ = 10m

Hence, wavelength is 10m
