the photoshpere emits visible light
It's something that emits its own light, and not just reflects it. An example of a natural source would be a star whereas the moon is not, even though it glows. The moon's light is due to reflection. Fast moving and highly charged ionic particle also can emit their own light, or something that has electrons which go from a higher energy state to a lower energy state, even though that light isn't always visible.
Colder stars emit red light. Hot stars emit large amounts of green light with small amount of red and blue light, which balances out to a white color in human eyes.
Luminous objects are things that let out light without the help of anything else. Examples are:The SunGlow wormsLight bulbsGlow sticksStarsLighted candlesSparksFlamesHeating coilsLEDsTV ScreensDischarge tube
Luminous means "giving off light", or glows in the dark (since luminosity is detected by the eyes, it usually refers to the visible part of the electromagnetic spectrum). Many materials emit a wide range of radiation other than visible light, which is why some radioactive materials were used as glow in the dark paints, and why the Curies focused on a particular radioactive isotope (because it glowed in the dark). Some materials can even store energy from visible light and emit it later, which is why some of my luminous objects have to be "charged" by a light bulb or the sun. Some chemical combinations can emit light for a while, such as the stuff in lightning bugs, which we can replicate in production lines to make glow sticks. Non luminous materials do not emit light that we can see. Most elements that are not radioactive fall into this category.
Things that give out light are called luminous objects. These objects emit their own light through a process called luminescence, which can be either incandescence (like a light bulb) or luminescence (like a glow stick). Non-luminous objects, on the other hand, reflect light from other sources without emitting their own light.
the sun only emit light. not the moon. it will reflect the light of the sun.
No. Planets do not emit light; they can only reflect light from the Sun.
The moon does not emit light waves. It reflects light from the sun. The sun, light bulb, and campfire emit light waves through processes like nuclear fusion or combustion.
All planets only reflect light. Only stars, like our sun, emit.
The sun emits light, and quite a lot of it.
No, candles emit light through combustion of a wick and wax, producing a warm yellowish light. The sun emits light through nuclear fusion in its core, producing a much brighter and whiter light.
Bubbles can emit light through a process called luminescence, where the molecules in the bubble emit light when they are excited. This can happen when the bubble is exposed to certain types of energy, like from the sun or a light source, causing the molecules to emit light as they return to their lower energy state.
The sun emits about 100,000 lux of light on a clear day.
Moonlight is almost entirely reflected sunlight, with very small amounts of reflected starlight and earthlight as well. As such, it radiates at the same continuous spectrum as the sun, though it won't have the bright emission lines that the sun emits.
A star emits light. Our Sun is a star.
The Moon only reflects light from the Sun.
Objects that emit light are usually referred to as incandescent.
