Surface waves travel slower than body waves.
There is Two types of surface waves :)
P waves... L waves are slowest.
Transverse waves.
The frequency of the waves is 0.20 HZ.
The four main types of brain waves are alpha, beta, theta, and delta. Alpha waves are associated with relaxation and wakefulness, beta waves with focus and alertness, theta waves with deep relaxation and meditation, and delta waves with deep sleep and unconsciousness.
Delta waves are associated with deep sleep and indicate relaxation. Theta waves are linked to daydreaming, creativity, and light meditation. The increase in delta and theta activity when the eyes are open could be due to the brain entering a state of relaxation or daydreaming while maintaining alertness.
From lowest to highest frequency, Delta, Theta, Alpha and Beta
"Theta waves" are irregular, though common in children, theta waves are uncommon in awake adults...but may appear when concentrating. ~jm~ A&P 201
The brain produces four distinct types of brain waves--delta, theta, alpha, and beta.the more relaxing alpha (8-13 Hz) and theta waves (4-9 Hz).are usually associated with deep, meditative states
In general, disease typically increases slow activity such as theta or delta waves, but decreases fast activity such as alpha and beta waves.

No, theta waves cannot be converted into power in the same way that electrical signals can be converted into usable power. Theta waves are a type of brain wave that are associated with relaxation and creativity, and are not a form of energy that can be harnessed for power generation.
During sleep, different brain waves are produced depending on the sleep stage. For example, during REM (rapid eye movement) sleep, the brain exhibits beta and theta waves, while in non-REM sleep stages, delta waves are prominent. Delta waves are associated with deep sleep and are typically seen in stages 3 and 4 of non-REM sleep.
Brainwaves are broken down into 4 main groups. Beta waves which we emit when we are in heightened emotional states. Alpha waves occur when we are moderately relaxed. This is also the state that we learn best in. Theta waves are generally reserved for states of meditations and light sleep. Delta waves are usually emitted while you are unconscious.
There are four stages of sleep: 1) Stage 1 is characterized by theta waves, 2) Stage 2 by sleep spindles and K-complexes, 3) Stage 3 by delta waves, and 4) Stage 4 by predominantly delta waves. As we progress through the stages, brain activity slows down, with deeper stages associated with slower wave patterns.
