Nonluminous describes something that does not emit its own light. It reflects or absorbs light from an external source rather than generating it internally. This term is often used in physics and astronomy to classify objects based on their light-emitting properties. nonluminous objects are visible only when illuminated by a light source, appearing dark or shadowy in the absence of light. The degree of visibility depends on the object's reflective properties and the intensity of the incident light. Examples include celestial bodies like planets and asteroids, as well as common earthly items like rocks and furniture.
Nonluminous meaning with examples
- The distant planet, being nonluminous, could only be observed through a powerful telescope as it reflected the dim light of its star. Scientists studied its surface composition based on how it reflected different wavelengths of light. Without the star's illumination, the planet would be invisible to us.
- A nonluminous cloud drifted across the sky. It blocked the sun and cast a dark shadow upon the land. Although seemingly dark, it was composed of tiny water droplets which would reflect the light back at different angles.
- The artist cleverly used a nonluminous charcoal to create dark, subtle shades in the portrait, contrasting them with brighter, luminous elements to give a depth to the work of art.
- The seemingly nonluminous surface of the moon only shines when it is illuminated by the sun's rays. The phases of the moon are the effect of the sun illuminating it's different positions.
- The museum displayed a collection of meteorites, many of which were nonluminous, only revealing their textures and features under specialized lighting, mimicking how they would appear in space.
