The film demonstrates the principles of optics, particularly how light behaves and interacts with objects. It explains that light travels in straight lines, which is evident in the formation of sharp ...

The double-slit experiment is one of the most famous experiments in physics and definitely one of the weirdest. It demonstrates that matter and energy (such as light) can exhibit both wave and ...

A LIGHT wave, when reflected 1 at the surface of separation of two media, may be altered in amplitude, or wavelength, or phase. Whilst, however, a change of amplitude or wave-length produces an ...
