WebWhen a beam of light crosses the boundary between a vacuum and another medium, or between two different media, the wavelength of the light changes, but the frequency remains constant. If the beam of light is not orthogonal (or rather normal) to the boundary, the change in wavelength results in a change in the direction of the beam. WebThe wavelength of light emitted by a laser depends upon the material from which the laser crystal, diode, or gas is composed. Lasers are produced in a variety of shapes and sizes, ranging from tiny diode lasers small enough to fit through the eye of a needle, to huge military and research-grade instruments that fill an entire building.
