Illumination=light, so a source of light
Eg. lightbulb, moon, sun etc.
Seiko men's diving watch doesn't have any source of illumination
When there is more than one source of illumination.
Illumination involves a source of light being emitted. To have visibility, the human eye requires illumination of light for things to be seen. Visibility is the state of being seen. To be visible you must have a level of illumination--a source of light.
The sun is a natural source of light that provides warmth and illumination to Earth.
Fire would be a common ancient source of light used by early humans for warmth, cooking, and illumination. Other ancient sources of light include candles, oil lamps, and torches.
The illumination on the surface would be reduced by a factor of four, thereforeif the distance from a light source is doubled, the illumination provided by the source is one fourth as great.

The illumination of a surface by a light source is directly proportional to the intensity of the light source and inversely proportional to the square of the distance between the light source and the surface. This relationship is described by the inverse square law of illumination.
when objects get lighted from other source of light it is known as illumination
The illumination on a surface decreases as the distance from the light source increases. This is because light spreads out as it travels, leading to a decrease in light intensity the further away from the source. The relationship between illumination and distance follows an inverse square law, where doubling the distance results in a fourfold decrease in illumination.
When there is more than one source of illumination.
Light does not cast a shadow because it is the source of illumination.
When there is more than one source of illumination.

The illumination intensity knob controls the brightness of the light source in a microscope. By adjusting this knob, you can increase or decrease the amount of light that shines on the specimen, helping to improve visibility and contrast for better microscopy observations.
