A star emits light because it is hot enough to emit electromagnetic waves in the visible spectrum.
The dense regions of a dark nebula are areas where interstellar dust and gas are more concentrated. These regions can sometimes lead to the formation of new stars through gravitational collapse. They appear dark because they block the light from background stars.
No, the sun is not green. The sun emits light in various wavelengths, including green, but it appears white to us because it emits light in all visible wavelengths.
Yes, a burning candle is luminous because it produces its own light through the process of combustion. The flame emits light and heat as a result of the energy released during the burning of the candle wax.
1) because the unit has a bulbous shape (the outer glass bit) 2) because the unit produces/emits light. The name is an exact description of that it does and its shape.
As the temperature of a star increases, the amount of light it emits increases. This is because hotter objects emit more energy in the form of light, including higher energy photons in the visible spectrum, leading to a brighter appearance.
No, a flame does not have a shadow because it emits light and does not block light from other sources.
No, fire does not have a shadow because it emits light and does not block light like solid objects do.
No, it only emits light. The heat gets radiated away as light.No, it only emits light. The heat gets radiated away as light.No, it only emits light. The heat gets radiated away as light.No, it only emits light. The heat gets radiated away as light.
Carbon nanotube emits light because it absorbs light across a wide range of wavelengths
intense gravitational pull that does not allow light to escape, creating a region called the event horizon. Once light crosses this point, it is unable to escape, leading to the black hole appearing to emit no light.

We can see the sun because it emits light and that light travels through space to reach our eyes on Earth.
Starburst galaxies are especially bright in infrared light because the high rate of star formation results in a lot of dust being heated up, which emits infrared light. This makes starburst galaxies stand out at these wavelengths compared to their normal counterparts.

...because the colour of an object depends on the wavelength of light it reflects, or the wavelength of light it emits.
