NEET Physics (general) Match the Following Question
Type: Match the Following-match the column-Medium-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Silicon | (i) E g > 3 eV |
| (b) Germanium | (ii) E g < 3 eV |
| (c) Insulator | (iii) E g = 1.1 eV |
| (d) Conductor | (iv) E g = 0 eV |
A
a-iii, b-ii, c-i, d-iv
B
a-ii, b-iii, c-i, d-iv
C
a-iii, b-i, c-iv, d-ii
D
a-iii, b-ii, c-iv, d-i
Correct Answer
Option A
Detailed Explanation
Silicon has a band gap of approximately 1.1 eV, which is less than 3 eV, thus it is classified under semiconductors. Germanium also has a band gap less than 3 eV, indicating its semiconductor nature. Insulators have a band gap greater than 3 eV, and conductors have no band gap.
