Which outcome occurs when a dielectric radio-frequency lens focuses microwaves?

A)Wavelength decreases; beams converge
B)Frequency decreases; constructive cancels
C)Amplitude increases; impedance matches
D)Phase shift reverses wave polarity

💡 Explanation

Microwave beams converge because refraction causes beam bending with the lens acting like prisms concentrating EM radiation. Consequently, wavelength decreases because beam bending maximizes transmission rather than inducing reflection or phase inversion.
