An object that doesn't give out light is called a non-luminous object. These objects do not emit their own light but can reflect light from other sources.
No, most objects do not give off their own light. Objects either reflect light from a light source or emit light when they are heated to a high temperature.
Luminescent.
Yes, light can bend around objects due to a phenomenon called diffraction. This bending of light waves is more noticeable when the wavelength of light is similar to the size of the obstacle. This can be observed in everyday situations, such as when light bends around the edges of a doorway or when viewing objects through a microscope.
Light sources are objects that emit light, such as the sun, light bulbs, and fire. Non-light sources are objects that do not emit light but can reflect or block light, such as books, walls, and clothes.
