Proper noun
(physics)
The
assumption
that
each
point
on
a
wavefront
may
be
regarded
as
a
source
of
secondary
waves
and
that
the
position
of
the
wavefront
at
a
later
time
is
determined
by
the
envelope
of
these
secondary
waves;
proposed
in
order
to
explain
the
fact
that
light
travels
in
a
straight
line
and
casts
sharp
shadows.
Japanese Meaning
物理学において、波面上の各点を二次波の発生点として考え、これらの二次波の包絡線によって波面の後の位置が決定されるという仮定。これにより、光が直進し、鮮明な影を作る現象を説明するための原理である。

Huygens' principle
In classical optics, Huygens' principle explains diffraction patterns by treating each point on a wavefront as a source of secondary waves whose envelope determines the subsequent wavefront.
