Light frequency from an incandescent lamp depends on the
A)amount of electrical energy transformed.
B)rate of atomic and molecular vibrations.
C)voltage applied to the lamp.
D)electrical resistance of the lamp.
E)transparency of glass.

Question

Quizplus · Accepted Answer

The frequency of light emitted by an incandescent lamp depends on the rate of atomic and molecular vibrations within the filament of the lamp. This is due to the fact that as the filament gets heated up due to the flow of electric current, the atoms and molecules within the filament start vibrating at a faster rate, and this causes the emission of light. The other options do not directly affect the frequency of light emitted by an incandescent lamp.
