Question

What is the nature of the spectrum found in light from the hot filament of a light bulb?

(A) Continuous spectrum
(B) Discrete spectrum
(C) Absorption spectrum
(D) Emission spectrum

Answer 1

The spectrum found in light from the hot filament of a light bulb is a continuous spectrum, which contains all wavelengths or colors of the rainbow.

Step-by-step explanation:

The nature of the spectrum found in light from the hot filament of a light bulb is a continuous spectrum.

A continuous spectrum is formed when a solid or very dense gas gives off radiation, resulting in an array of all wavelengths or colors of the rainbow. This is in contrast to a line spectrum, which consists of only certain discrete frequencies or wavelengths.

• Example: When white light passes through a prism, it separates into a continuous spectrum of all colors.
