Potassium ions will emit visible light when excited, for example during a flame test. We see this as a lilac colour.
They are classified by the amount of Light they give off, and their temperature.
Some methods to conserve energy include turning off lights and electronics when not in use, using energy-efficient appliances and light bulbs, implementing smart thermostats to regulate heating and cooling, sealing air leaks in windows and doors, and enhancing insulation in your home. Additionally, utilizing natural light and ventilation whenever possible can help reduce energy consumption.
The light given off by electric discharge through sodium vapor appears as a bright yellow-orange color. This is because sodium vapor emits light in the yellow part of the spectrum when energized by an electric current. This phenomenon is utilized in street lamps and other high-intensity discharge lighting systems.
If light bounces off a mineral, it has a shiny or reflective surface. This property is known as luster, and minerals can exhibit a range of lusters, including metallic, vitreous (glassy), pearly, or dull. Luster is one of the key characteristics used to identify minerals.
Yes , some creatures are bio-luminescent such as fireflies and deep sea animals .
A luminous object is something that emits/gives off light - eg sun, star, light bulb, A non-luminous object is something that doesnt have/give off its own light - eg moon, diamond, wood. Non-luminous objects can only be seen because they reflect light, which is given off by luminous objects.

An object that gives off its own light is called a luminous object. Some examples include the sun, a light bulb, or a burning candle.
no the moon isn't luminescent because the sun light shines off the moon and that's why we see it ( why it glows ) and that's why when we have eclipses it alters how the moon looks because depending on how much or how little sun light can get through changes the color.
yes it does give off light
If the powder is luminescent or phosphorescent, it will glow in the dark for a period of time after the light is turned off due to stored light energy being slowly released. If the powder is just regular powder without any special properties, it will remain dark once the light is turned off.
The phrase 'give off light' means to have a lot of light.
Give her something in trade for the TV
Planets and Moons only reflect light, they do not 'give off light'.
No, our sight comes from light rays reflecting off of the object and coming into our eyes. Without a source of light that's not the object, the object itself must be luminescent (emitting it's own light).
