A) \[10\times {{10}^{14}}Hz\]
B) \[5\times {{10}^{14}}Hz\]
C) \[1\times {{10}^{14}}Hz\]
D) \[20\times {{10}^{14}}Hz\]
Correct Answer: B
Solution :
\[p-n\] photodiode is a semiconductor diode that produces a significant current when illuminated. It is reversed biased but is operated below the breakdown voltage. |
Energy of radiation = band gap energy |
i.e., \[hv=2.0\text{ }eV\] |
or \[v=\frac{2.0\times 1.6\times {{10}^{-19}}}{6.6\times {{10}^{-34}}}\] |
\[\approx 5\times {{10}^{14}}Hz\] |
