Question
The distribution of light on a horizontal surface is known as
- Group of answer choices
- luminescence.
- luminosity.
- illuminescence.
- illumination.
Solution
The correct term for the distribution of light on a horizontal surface is illumination.
Explanation:
- Luminescence refers to the emission of light by a substance that has not been heated, including various phenomena such as fluorescence and phosphorescence.
- Luminosity is a measure of the total amount of light emitted by a star or other celestial object, and it is often used in the context of astrophysics.
- Illuminescence is a less common term and is often confused with luminescence, but it generally refers to the light emitted through a process other than thermal radiation.
In contrast, illumination specifically describes the amount and distribution of light that reaches a surface, making it the most appropriate term for this context.
