Both mercury the metal and Mercury the planet reflect light quite well.
it takes about 3-4 minutes for light to travel to mercury
Without the mercury in a CFL you wouldn't have light. The ballast in a CFL supplies initial current which excites the mercury which releases photons, or light. The mercury does not produce visible light, this happens only once the light passes through the phosphor coating on the inside of the bulb.
A mercury light typically emits multiple wavelengths of light. It produces a line spectrum with several distinct wavelengths corresponding to the transitions of electrons within the mercury atoms. Typically, a mercury light will contain several prominent wavelengths in the ultraviolet and visible light ranges.
yes
It doesn't produce light.
Mercury Is 0.000131 lightyears away from earth
A mercury vapor light works by passing an electric current through mercury vapor inside a sealed tube. This process causes the mercury vapor to emit ultraviolet light, which then excites a phosphor coating on the inner surface of the tube to produce visible light.
Mercury shines by reflecting light from just one single star: our Sun.
Yes. Argon and mercury are present.
No, not in the filament. You are probably thinking of compact fluorescent light bulbs, which do contain mercury.
Mercury is very light. And will react more to heat.
