Incident light is the light that falls from the source onto the subject. It is usually measured with a hand-held instrument (often digital, these days) called an incident-light meter. Readings are usually taken from the subject's position, with the receptor-cell of the meter facing back toward the camera. Some incident-light meters are dedicated to that function. Others can measure "reflected" light (light that is reflected from the subject) and have a module for measuring incident light as well.

What is an albedometer?
An albedometer is an instrument used to measure the albedo - the fraction of incident light or radiation reflected by a body - of a surface.

Do opaque object absorbs all the incident light on it?
Be careful not to confuse: Opaque objects are those that do not allow light to pass through it, but they can reflect light. It is BLACK objects that absorb all the incident light on it. To conclude, opaque objects do not necessarily absorb all the incident light on them but black objects ABSORB all the incident light on them (and are, of course, opaque)
How does incident light emerge from a prism?
Incident light hits a prism, refracted or reflected light emerges from it. In what manner it is different from the incident light depends on the angle of incidence and the angles of the prism. Commonly it may be refracted, dispersed or reflected back.
What object could you use to measure the brightness of the bulb?
An item called a LUX meter is usually used for the determination of the brightness of a light bulb. It is generally a meter that measures the amount of incident white light.
What will be the color reflected by a green surface when yellow light is incident on it?
No light will be reflected, since there is no incident green light to reflect. To a human observer, the surface will appear black.
The ingoing ray of light?
The ingoing ray of light is the incident ray
What is the name for a beam of light used to represent a light path?
Incident light ray
What absorbs incident light?
Anything dark
What are the metrics that can be used to measure the efficiency or effectiveness of Incident Management?
The following metrics can be used to measure the efficiency/effectiveness of Incident Management: • The percentage of Incidents resolved within SLA • The average cost of an Incident • The average cost of a Major Incident • The percentage of Incidents that are Major
When the color of an object is the color of the light it?
The object reflects all the incident light.
