we use mercury lamp instead of ordinary lamp because ordinary lamp has many wavelengths when mercury lamp has single wavelength so in constant deviation we use only mercury lamp.
the supply voltage to a mercury vapour lamp (from the electromagnetic ballast) is 130vac
No. A mercury vapor lamp will work on a metal halide ballast, but not the other way around.
yes, there is a coating in the lamp, which contain mercury
It is a High Pressure Mercury Vapour lamp.

Yes i can. there is polychromatic in the rainbow.
for diffraction grating mercury lamp is used not sodium lamp.
Polychromatic means "multicolored" in English. The Greek word for polychromatic is πολυχρωματικό
It is a gas discharge lamp which uses mercury in excited states.

No you can't. You can use a metal halide lamp of the exact wattage of the original mercury lamp. You cannot vary on wattage at all.
You might say that a rainbow is polychromatic having various colours
Yes, but in minute amount
