Q40. Consider a metal with free electron density of 6x10 cm. The lowest frequency electromagnetic radiation to which this metal is transparent is 1.38x10° Hz. f this metal had a free electron density of 1.8x10 cm instead, the lowest frequency electromagnetic radiation to which it would be transparent i... two decimal places). ..x10° H: (up to
