← ScienceWhich outcome arises when a high-frequency electromagnetic wave propagates through a dielectric material within a parallel-plate capacitor?
A)Dielectric polarization and energy absorption✓
B)Increased wave velocity and transparency
C)Perfect wave transmission, refraction absent
D)Reflected wave amplification, cavity resonance
💡 Explanation
Dielectric materials exhibit polarization when exposed to oscillating electric fields, therefore this causes energy absorption from the high-frequency wave via dielectric losses; rather than increased transmission because material properties induce drag on the electromagnetic propagation.
