A hot plasma has a plasma frequency of 1 MHz. A radio wave of frequency 900kHz incident on the plasma. What happens to the wave? 16 Select one: O a. The wave passes through the plasma and experiences dispersion O b. The wave is refracted by the plasma O c. The wave is reflected and an evanescent wave forms inside the plasma O d. An evanescent wave is reflected from the plasma
