(1) An orbital can be defined by four quantum numbers
(II) Absorption spectra are used to identify elements in the outer part of starts
(IIT) Spectral degeneracy in magnetic field is observed only in single electron species
(IV) In black body radiation, the intensity of radiation is directly proportional to T.
(A) (I) and (ID) (B) (II), (III) and (IV) (C) (1) and (II) (D) (1). (II) and (III​

Answer 1

Answer:

sorry I don't know the answer

Answer 2

Answer:

C 1 and 2 are correct

Explanation:

An orbital can be defined by for quantum numbers l,n,m,s.

And Absorption and spectra is used identify the atoms with which the stars is made up of because every atom has a unique spectra.Isnt it amazing we can identify atoms of stars sitting at Earth.

Hope its helps.
