Brain waves are described by examining their:
A) frequency and altitude
B) frequency and amplitude
C) pitch and amplitude
D) size and depth

Question

Quizplus · Accepted Answer

Brain waves are typically identified and differentiated based on their frequency (measured in Hertz) and amplitude (measured in microvolts). These two factors help to classify brain waves into particular types, such as alpha, beta, delta, and theta waves. Pitch and altitude are not relevant to brain waves, and size and depth are not precise enough descriptors for the electrical activity of the brain.
