Question

1. Can a waveguide have more than one cut-off frequency? On what factors does the
cut-off frequency of a wave guide depend?
​

Answer 1

Answer:

Explanation:

The cutoff frequency of an electromagnetic waveguide is the lowest frequency for which a mode will propagate in it. In fiber optics, it is more common to consider the cutoff wavelength, the maximum wavelength that will propagate in an optical fiber or waveguide.

yes it have can have more than one cut off frequency

the factors on which cut off frequency of a waveguide depends are two peremitres

internal resistance and its capacitance
