Pick out the correct statement from the following

Options

A. Mercury vapour lam produces lines emission spectrum
B. Oil flame produces line emission spectrum
C. Band spectrum helps us to study molecular structure
D. Sunlight spectrum is an example for line absroption spectrum

Answer

A, C, D

Explanation

The line emission spectra is produced by excited substance in atomic state, as by mercury vapour lamp. Line absorption spectra state, is produced by e.m. ratiations, that has passed through a medium hence, sunlight spectrum is a line absorption spectrum. The Band spectrum is used to study the molecular structrue. Here,a,c, and d are the correct statements.
