Question

select the correct answer.
which factor is not a type of spectra?
a. emission
b. absorption
c. continuous
d. discontinuous

Explanation:

In physics, there are three main types of spectra: emission spectra (produced when atoms emit light), absorption spectra (produced when atoms absorb light), and continuous spectra (produced by a hot, dense object like a black - body radiator). There is no such thing as a "discontinuous" spectrum type in the standard classification of spectra.

Answer:

D. discontinuous
