Final answer:
An awake and alert person will present beta waves during a brain wave test. These occur during wakefulness and they have a very low amplitude and a high frequency (13-30 Hz). Other types of brain waves, such as alpha, theta, and delta waves, are characteristic of different stages of sleep, with alpha indicating drowsy relaxation, theta linked to light sleep, and delta reflecting deep sleep.
Step-by-step explanation:
If an awake and alert person undergoes a brain wave test, it will typically reveal beta waves. These are a type of brain wave characteristic during wakefulness, which have a very low amplitude and high frequency ranging between 13-30 Hz. That means they occur quite frequently (13-30 times per second) but have a small height on an EEG reading.
The brain produces different types of waves depending on our state of consciousness -- whether we are alert, relaxed, or in various stages of sleep. During wakefulness, when a person is alert and thinking, beta waves are most common. But when a person is falling into sleep, alpha waves are prominent, typically followed by theta and then delta waves as the sleep deepens.
So, to answer the question, an awake and alert person will likely present beta waves during a brain wave test.
