Is a lava a luminous object?

Answer 1

Yes, typically lava glows red, orange, yellow, or white before it cools sufficiently to harden and become a black solid. So, while it is still hot enough to remain a viscous liquid, it gives off light, making it luminous.

Answer 2

Diamond is a non-luminous object as it doesn't have its own light but it can absorb and reflect the light.

Answer 3

No, lava is not a luminous object in and of itself. Lava is molten rock that is extremely hot and glows red or orange due to its high temperature. The glow of lava is a result of incandescence, which is the emission of electromagnetic radiation (light) caused by the high temperature of the lava. However, this does not make lava a luminous object in the same way that a light bulb or the sun is considered luminous.

Answer 4

Lava itself is not inherently luminous as it is molten rock exposed to high temperatures. However, when lava flows at night or interacts with other elements like gases or water, it can emit a glow due to incandescence, making it appear luminous.

Answer 5

Diamond is not luminous it is non luminous it does not give light on its own

Answer 6

Luminous objects emit their own light. When a piece of charcoal is room temperature it is not a luminous object, but when it is burnt and glowing, it becomes a luminous object.

Answer 7

Yes a Star produces light energy (photons) and so is a luminous object.

Answer 8

No, it just has a very flat surface, meaning that all the light that hits the mirror is instantly reflected, giving it the properties.

Answer 9

Radium is a radioactive element. It is not luminous, but it can be used to make other substances luminous.

Answer 10

diamonds are non luminous. they emit light when light strikes it
