Question

RRB Paper · Accepted Answer

In a mercury vapor lamp light red objects appear black due to absence of red light from lamp radiation. Mercury vapor lamps produce light by passing an electric current through a gas mixture that includes mercury vapor. The resulting radiation includes wavelengths of light in the ultraviolet, blue, and green parts of the spectrum, but very little red light is emitted. When this light falls on an object, the object will reflect some wavelengths of light and absorb others. If an object appears red, it is reflecting mostly red light and absorbing other colors.

In a mercury vapor lamp light red objects appear black due to

High wavelength of red objects

Color mixing

Absence of red light from lamp radiation

Absorption of red light by the lamp radiation
