← ScienceWhich outcome arises when a discontinuity impedes microwave propagation?
A)Increased standing wave ratio✓
B)Enhanced waveguide mode purity
C)Decreased dielectric material breakdown
D)Minimized conductor surface resistance
💡 Explanation
An impedance mismatch causes wave reflection, therefore increasing standing wave ratio, because impedance differences create reflected microwaves. Rather than mode purity or dielectric breakdown, the primary effect concerns reflected power.
