If two waves meet each other in step, they add together and reinforce each other. They produce a much higher wave, a wave with a greater amplitude.
Holography - an overview | ScienceDirect Topics
A. Pepper, in Encyclopedia of Modern Optics, 2005 Introduction. Holography captures the phase and amplitude of light reflected from, or transmitted through, an object. In visual terms it captures ‘true’ three-dimensional space and any objects which are placed within that space. This is very different from the various optical illusions, including perspective drawing and painting, which,Vibration Analysis Explained | Reliable Plant,Vibration analysis is generally broken down into four principles, and each principle gives you specific information on the working conditions and features of the vibrating parts.
