The Dutch scientist Christiaan Huygens (1629–1695) developed a useful technique for determining in detail how and where waves propagate. Starting from some known position, Huygens’s principle states that every point on a wave front is a source of wavelets that spread out in the forward direction at the same speed as the wave itself. The new wave front is tangent to all of the wavelets.
Christiaan Huygens ( [ˈhœyɣəns] IPA ( výslovnost) 14. dubna 1629, Haag – 8. července 1695, Haag) byl význačný nizozemský fyzik, matematik, astronom, horolog a autor rané science fiction. K jeho zásluhám patří teleskopická pozorování vesmíru, díky nimž vysvětlil povahu prstenců kolem Saturnu a objevil jeho měsíc Titan ...

Huygens’ wavelet. envelope. Huygens’ principle, a statement that all points of a wave front of sound in a transmitting medium or of light in a vacuum or transparent medium may be regarded as new sources of wavelets that expand in every direction at a rate depending on their velocities. Proposed by the Dutch mathematician, physicist, and ...
12. Aug. 2012 · Christiaan Huygens: Discoverer of Titan. Born in 1629, Huygens came from a wealthy and well-connected Dutch family, who served in the diplomatic service to the House of Orange. As a young boy he showed promise in mathematics and drawing. In 1645 he went to the University of Leiden to study mathematics and law.
The Huygens–Fresnel principle (named after Dutch physicist Christiaan Huygens and French physicist Augustin-Jean Fresnel) states that every point on a wavefront is itself the source of spherical wavelets, and the secondary wavelets emanating from different points mutually interfere. [1] The sum of these spherical wavelets forms a new wavefront.
