What is the frequency of Beta waves?

Explanation:
Beta waves represent higher-frequency brain activity, typically defined as above 13 Hz (roughly 13–30 Hz). They’re associated with active thinking, concentration, and alert wakefulness. That’s why the frequency category above 13 Hz is the correct one. For context, theta is about 4–7 Hz and links to drowsiness or light sleep, delta around 0.5–4 Hz with deep sleep, and alpha about 8–13 Hz seen during relaxed, eyes-closed wakefulness. So the beta range is the higher end of the spectrum, above 13 Hz.
