Detailed explanation-1: -Beta waves are high-frequency, low-amplitude brain waves that are commonly observed in an awaken state. They are involved in conscious thought and logical thinking, and tend to have a stimulating effect. Having the right amount of beta waves allows us to focus.
Detailed explanation-2: -Wake Stage: Alpha and Beta Waves Both alpha and beta brain waves are present during the wake stage. Beta wave activity is predominant during eye-open wakefulness. Beta waves, the most common daytime brain waves, are associated with engaging activities, such as problem-solving and other cognitive tasks.
Detailed explanation-3: -Alpha waves are seen in the electroencephalogram (EEG) during a normal wakeful state where the subject is quietly resting. Beta EEG are present when a person is alert/attentive and thinking actively. Theta rhythm (Stage 1) of sleep is present during the transition from wakefulness to sleep.
Detailed explanation-4: -The waking state with the eyes open is characterized by high-frequency (15–60 Hz), low-amplitude activity ( 30 V) activity. This pattern is called beta activity.
