Calibrate 16 types of RTDs, and 13 types of thermocouples with our handheld multifunction process calibrator. Multifunction Process Calibrators Our multifunction process calibrators read and source RTD, thermocouple, current, voltage, frequency, and resistance to calibrate or verify your process sensors.
Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes radiate seismic energy as both body and surface waves. Body Waves The first kind of body wave is the P wave or primary wave. This is the fastest kind of seismic wave. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth. It pushes and pulls the rock it moves through just like sound waves push and pull the air.
A: Sound waves travel fastest through a solid material. The second fastest medium is a liquid, and the slowest medium is a gas, because sound waves travel by vibrating molecules in a medium. In solids, these molecules are spaced closer together, causing sound to travel faster through it. Continue Reading
