Physics-(general)
NEET Physics (general) Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
Column-I Column-II (a) Valence band (i) Completely empty at absolute zero (b) Conduction band (ii) Completely filled with electrons (c) Energy gap (iii) Separation between two energy bands (d) P-N junction (iv) Allows controlled flow of electrons
Choose the correct matching:
A
a-ii, b-i, c-iii, d-iv
B
a-i, b-ii, c-iv, d-iii
C
a-ii, b-iv, c-i, d-iii
D
a-iv, b-iii, c-i, d-ii
Correct Answer
Option A
Detailed Explanation
The valence band is completely filled with electrons at absolute zero, while the conduction band is completely empty at that temperature. The energy gap represents the separation between the valence and conduction bands, and the P-N junction allows for a controlled flow of electrons.
