Explanation / Answer

Question 24: D) Delta waves

Delta waves could be recorded when a person is asleep. These could be recorded by the use for electroencephalogram ( EEG). These waves are normally found in the 3rd stage of sleep, deep sleep referred to as the NREM sleep. This Kind of sleep is also referred to as the slow wave sleep and this is the kind of waves that help in determination and characterisation of the sleep and its depth. These are the waves that would be observed to be showing highest amplitude in the waves and are the slowest. In this stage of sleep, there would be a decrease in the heart rate, also referred to as delta sleep.
