波面(はめん)

はめん
noun
wave surface; wavefront
1. wave surface; surface of waves
The surface of water as shaped by waves.
波面(はめん)が光(ひかり)を反射(はんしゃ)する。
The wave surface reflects light.
風(かぜ)で波面(はめん)が細(こま)かく揺(ゆ)れている。
The surface of the waves is rippling finely in the wind.
夕日(ゆうひ)が波面(はめん)にきらきらと映(うつ)っていた。
The setting sun sparkled on the surface of the waves.
2. wavefront
In physics, a surface connecting all points of a wave that are in the same phase of oscillation.
波面(はめん)の形状(けいじょう)を測定(そくてい)する。
To measure the shape of the wavefront.
光学(こうがく)では波面(はめん)のゆがみがレンズの収差(しゅうさ)につながる。
In optics, distortion of the wavefront leads to lens aberration.
球面(きゅうめん)波(は)の波面(はめん)は点光源(てんこうげん)から同心円状(どうしんえんじょう)に広(ひろ)がる。
The wavefront of a spherical wave spreads concentrically from a point source.

Composed of 波(は) (wave) + 面(めん) (surface). Has both an everyday literary sense (the visible surface of water with waves) and a technical physics sense (wavefront). The literary sense appears in nature descriptions, while the technical sense is used in optics, acoustics, and wave physics.

COMMON COLLOCATIONS:

  • 波面(はめん)の揺(ゆ)れ: rippling of the wave surface
  • 波面(はめん)収差(しゅうさ): wavefront aberration (optics)
  • 波面(はめん)補正(ほせい): wavefront correction

SIMILAR WORDS:

  • 水面(すいめん): water surface — the flat surface of water regardless of waves
  • 海面(かいめん): sea surface — specifically the surface of the ocean
  • 波頭(はとう): wave crest — the peak of a wave, not the entire surface
