1. Crest - the point on a wave with the largest positive value or displacement up in a cycle. 2. Electromagnetic radiation - a plethora of wave disturbance in space which is the self-perceived phenomenon by the human eye as light. 3. Ultrasound - A term of trade for the use of high intensity acoustic energy change material 4. Analog? (To be more precise) 5. Amplitude - The magnitude of change in an oscillating system. 6. Pit - in front of Crest 7. - Waves sound vibrations transmitted by an elastic solid, liquid or gaseous, consisting of frequencies that can be detected by the organs of hearing. 8. Frequency - A measure of the number of occurrences of a repeating event per unit time. 9. Digital - a digital system uses discrete (or discontinuous) values to represent information for input, processing, transportation, storage, etc. 10. Geosynchronous orbit - an orbit around the Earth with an orbital period corresponding to the period of the Earth sidereal rotation.
