Answer:

theta waves with sleep spindles and K-complexes

Explanation:

K-complexes and sleep kindles are known to be defining brainwaves of stage 2 REM or sleep. Duke has not entered the deep sleep stage or the slow wave sleep stage which are characterized by low frequency and high delta waves. While K-waves are large theta waves that usually occur in response to stimulus such as sound, and hence Duke must have been awakened by the sound of the door.
