The wavelength of a wave with propagation constant (0.1

Home » Electromagnetic Theory » Electromagnetic theory miscellaneous » Question

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

1. 2/√0.05 m
2. 10 m
3. 20 m
4. 30 m

Correct Option: B

On comparing, given equation
γ = 0.1 π + j 0.2 π with
standard equation γ = α + jβ
β = 0.2 π
Now,

λ =	2∏	=	2∏	= 10 m
	β		.2∏
