James is a graduate student working in a sleep lab. He is analyzing EEGs, focusing on the height of the waves. Based on this information, what specific aspect of the EEGs is James studying?

• A. Frequency
• B. Amplitude
• C. Wavelength

Answer: (B)

Verified step by step guidance

1. Understand that EEGs (electroencephalograms) are used to measure electrical activity in the brain, represented by wave patterns.
2. Recognize that the 'height of the waves' in an EEG refers to the vertical measurement from the peak to the trough of the wave.
3. Identify that this vertical measurement is known as 'amplitude,' which indicates the strength or intensity of the brain's electrical activity.
4. Differentiate between amplitude and other aspects of EEG waves, such as frequency (the number of waves per second) and wavelength (the distance between successive peaks).
5. Conclude that James is specifically studying the amplitude of the EEG waves, as it relates to the height of the waves he is analyzing.
