It discusses the role of wave interference in producing holograms, using sound and light waves as examples. The film demonstrates the use of lasers to capture and reconstruct images through ...

Interference is the process in which two or more waves of the same kind come together, and they can add so as to reinforce one another or they can combine so as to cancel one another. For example ...

The interference of waves is determined in part by the wavelength ... A kicked football (for example) has a very tiny wavelength compared to the size of the ball because it has a relatively ...

Such unstable wave groups propagate independently regardless of interference. Results seem to support the concept of an unperturbed nonlinear water wave group focusing in the presence of counter ...
