Optics is the science that deals with the
creation,
nature, and properties of
light and the interaction of light with
matter. The field of optics describes the behavior of
visible,
infrared, and
ultraviolet light. Optics is a sub-field of
electromagnetism. Light is part of the
electromagnetic spectrum that extends from
x-rays to
microwaves which includes the
radiant energy that produces the
sensation of vision. Visible light is the wavelengths of light
that are visible to the
human eye. Equipment has been developed to view and record
light, such as the
camera.
Engineers of
optical devices and professional
photographers have studied the
physics of light to help control the effects of light such as
aberrations,
diffraction,
dispersion,
distortion,
interferometry,
polarization,
reflection,
refraction,
scattering. |
