What is the frequency of Theta waves?

Explanation:
Theta waves sit in the 4–7 Hz range. This frequency band sits between the slower delta (about 0.5–4 Hz) and the faster alpha (about 8–13 Hz) bands. In sleep EEG, theta activity is most associated with drowsiness and the transition into sleep, particularly stage N1, and can also show up during certain cognitive processes. That’s why 4–7 Hz is the correct range for Theta. The other options correspond to other rhythms: 8–13 Hz is Alpha, 0.5–2 Hz falls within Delta, and anything above 13 Hz is Beta.
