An evacuated waveguide has rectangular cross-section with dimensions 24 mm by

An evacuated waveguide has rectangular cross-section with dimensions 24 mm by 12 mm. i. What is the lowest frequency that can propagate in the waveguide in a TE mode, and in which mode? [3] li. A pulse is traveling along this waveguide in the same mode as above and with a frequency of 12.5 GHz. If the waveguide is 35 m long, how much time does this pulse take to reach the far end of the waveguide? (4]
