Common types of industrial motor controls include, but are not limited to, combination starter, industrial pump, magnetic coil, magnetic contactor, magnetic starter, manual starter and control relay.
Refraction of Light. Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. The amount of bending depends on the indices of refraction of the two media and is described quantitatively by Snell's Law.
