An air-filled rectangular waveguide has dimensions 8cm x 10cm . The phase velocity of guided wave at frequency of 3 GHz for TE10 mode is

[A].	1.5 x 10 8 m/s
[B].	5.5 x 10 8 m/s
[C].	3.46 x 10 8 m/s
[D].	0.18 x 10 7 m/s

Answer: Option C

Explanation:

4-797-68-1

4-797-68-2 4-797-68-3

∴ V_P = 3.46 x 10⁸ m/s.
