An optical and electrical phenomenon in which a material becomes less electrically conductive due to the absorption of electromagnetic radiation

A thermal and electrical phenomenon in which a material becomes less electrically conductive due to the absorption of electromagnetic radiation

A mechanical and electrical phenomenon in which a material becomes more electrically conductive due to the emission of electromagnetic radiation

An optical and electrical phenomenon in which a material becomes more electrically conductive due to the absorption of electromagnetic radiation (correct)

The energy absorbed enables the transition of activator electrons into the conduction band and the charge exchange of traps with holes being created in the valence band (correct)

The energy absorbed causes the material to become more insulating

The energy absorbed creates more traps in the valence band

The energy absorbed disables the transition of activator electrons into the conduction band and the charge exchange of traps with holes being created in the valence band
