Solved Problems on Cutoff Wavelength,Cutoff Frequency,Group Velocity,Phase Velocity,guide Wavelength 

Too good

are these formulae applicable to all rectangular wavequide numericals irrespective of the mode or dimensions ? Pls answer ❤

Consider a rectangular waveguide with dimesnsions 2.38cm×1.11cm. Find the cut off frequency. What TE mode will propagate in this waveguide if the driving frequnency is 1.7×10^10HZ? Sir pls give the solve of this problm

Sir can u plz explain cut off frequency and wavelength conpect

If TM and TE mode is not given then what is value of M and N

is it propagate or not withrespect to cut off wave lenth
