A star emits light because it is hot enough to emit electromagnetic waves in the visible spectrum.
No. It shines because it is reflecting light from the sun.
A candle is a luminous object because it emits to light by itself
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.
The Sun does this, of course.
A large celestial body that is composed of gas and emits light is called a star.
a black hole emits no light because of its high gravity
Because it emits light.
No. It shines because it is reflecting light from the sun.
Because it emits a beam of light - which is detected by a special membrane on the computer screen.
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
A candle is a luminous object because it emits to light by itself
is a type of chemical when exposed to radiation emits visible light.
...because the colour of an object depends on the wavelength of light it reflects, or the wavelength of light it emits.
true
the photoshpere emits visible light
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.
