Our eyes cant perceive motion faster than 1/10 of a second and light can travel about 10,000m in 1/10seconds. Since a normal room is on an average 7m x 7m, there is no observable delay in between turning on a light and seeing the emitted light.
bismuth will contain 81 protons turning into Thallium with an atomic number of 81. If it emits a beta particle it doesn't change its still bismuth, only it become more energetic.
a black hole emits no light because of its high gravity
dude..
When an electron returns to its ground state it emits energy in the form of light.
The electrons of the atom move closer to the nucleus while the atom emits light.

One emits light in the ultra-violet range, and the other emits light in the infrared range.
Flourescence is the ability of a material to emit light instantaneously in responses to excitation. Immediately emits light. Phosphorescence is the ability of a material to delay emission of light in response to excitation. Delayed emission of light.
A vaporizer emits a continual visable spray of warm steam, while a humidifier emits invisible moisture into the room. Most doctors recommend a humidifier over vaporizers.
In a directly heated cathode, the filament is the cathode and emits the electrons. In an indirectly heated cathode, the filament or heater heats a separate metal cathode electrode which emits the electrons.
Brass is a much softer alloy than bronze. The term "brassy", which refers to the sound that the metal emits, explains the sound it emits. Bronze has a more tonal quality to its sound.
The word "emits" is pronounced as ih-mits.
it emits very high energy photons
Neon emits a red to orange colour
It emits a high pitch
They both only allow current in one direction, but the LED emits light when current is flowing.
The female emits eggs, the male emits sperm.
