Question

Karina Robledo · Accepted Answer

Final Answer : B, Explanation :  Alpha waves are observed when a person is awake but relaxed, such as when falling asleep. Delta waves are associated with deep sleep, sleep spindles occur during stage 2 sleep, and rapid eye movements occur during REM sleep. As Jordanna has not yet fallen asleep, it is unlikely that any of the other wave patterns would be present on the electroencephalograph.
