Light falling on an object. The colour of an object is perceived as a function of the wavelengths of incident light reflected or absorbed by it.
All forms of light which reach the subject.
Light that shines onto the face of a solar cell or module.
Amount of light directly over an object.
The light actually falling on a subject, which may not be the same as the amount of light being reflected by the subject.
Light falling on a surface as opposed to the light reflected by it.
Light falling on a surface (as opposed to reflected by it). (see Meter)
is the light falling on a subject before it has been reflected by that subject. Some light meters measure incident light and others measure reflected light. A camera's built-in metering system measures reflected light only.
Light falling on the subject, rather than that reflected by it. Incident light readings are usually the most reliable way of working out the exposure, especially when taking slides.
Light falling directly on a subject; exposure for incident light is often measured in the lighting studio using a light meter with a wide angle of acceptance.
light that strikes a metal surface in the photoelectric effect.
The incident light is the amount of light reaching an object.
How much light that is on an object.
Light striking the surface of an object.
Incident light is light that falls on your subject.
light that falls on a subject (as opposed to the amount of light the subject reflects).
Light which falls directly onto an object.
A ray of light that falls on the surface of a lens or any other object. The "angle of incidence" is the angle made by the ray with a perpendicular (normal) to the surface. Index of Refraction For a specific material, the ratio of the speed of light in a vacuum (c) to the speed of light in the material. Because the speed of light in vacuum is faster than in any material, the index of refraction is always greater than 1.
Light falling on a surface rather than the light reflected by it.
A ray [or rays] of light that strikes an optical surface or other object. The angle of incidence is the angle made by the striking beam from perpendicular.
The light that is falling directly over an object.
The light that falls directly on an object.
Light as measured as it falls on a surface, rather than light reflected from a surface.
The light falling directly on an object.
The light, which hits a surface. This light, provided it is not reflected light from, or refracted through, another surface has the full colours of the spectrum represented in its wavelength.
