Meaning and Definition
A fundamental concept in wave theory stating that every point on a wavefront is a source of secondary wavelets, and the new wavefront is the envelope of these secondary wavelets.
A method of analysis used in physics (especially optics and acoustics) to predict and explain wave propagation, diffraction, and interference. It underpins the understanding of how waves spread and bend around obstacles.

FAQ
Frequently Asked Questions
It was proposed by the Dutch physicist, mathematician, and astronomer Christiaan Huygens in his 1690 work 'Traité de la Lumière' (Treatise on Light).
Yes, as a cornerstone of classical wave optics, it remains fundamentally valid and is extensively taught. For quantum mechanical waves or advanced electromagnetic theory, more sophisticated formalisms (like Kirchhoff's diffraction formula) are used, which can be seen as mathematical extensions of Huygens' original idea.
Huygens' original principle described wave propagation but could not fully account for interference and diffraction patterns. Augustin-Jean Fresnel later added the crucial concept of interference between the secondary wavelets, creating the Huygens-Fresnel principle, which successfully predicts detailed diffraction effects.
Yes, in its classical form, it applies to any linear wave phenomenon, including light waves, sound waves, and water waves. It is a general geometrical construction for understanding wave propagation.
A fundamental concept in wave theory stating that every point on a wavefront is a source of secondary wavelets, and the new wavefront is the envelope of these secondary wavelets.
Huygens' principle is usually technical / scientific in register.

Mnemonic
Imagine throwing a pebble into a pond; the ripple is a wavefront. Each water molecule in that ripple becomes a tiny new pebble, creating its own tiny ripple. Huygens' principle says the next big ripple is just the combined edge of all these tiny ripples.
Conceptual Metaphor
A WAVEFRONT IS A COLLECTION OF POINT SOURCES.
