Q1: For a circular wave guide

A cutoff frequency for TE10 and TE01 modes are same

B cutoff frequency for TE10 and TE01 modes are different

C cutoff frequency for TE10 mode = twice the cutoff frequency for TE20 mode

D cutoff frequency for TE10 mode = haf the cutoff frequency for TE20 mode

ANS:A - cutoff frequency for TE10 and TE01 modes are same

When a circular waveguide is rotated by 90°, the configuration remain the same.
