The brain waves that exhibit the lowest frequency, as well as highest amplitude, are called Theta waves.
In an electroencephalogram (EEG) recording, a wave represents any kind of brain activity that is registered in the form of a wave. These waves are of distinct kinds. Theta waves exhibit a frequency of four to seven waves per second. These types of waves with the lowest frequency depict slow activity in the brain but also have the strongest signal due to the highest amplitude.
The other brain waves include Alpha waves, Beta waves, etc. The Alpha waves have a frequency of about 8 to 13 waves per second.
