BITSAT Physics Question (2024) — Solution

Question

The acceptor level of a p-type semiconductor is 6 eV . The maximum wavelength of light which can create a hole would be : Given hc =1242 eV nm .

Options

  1. A. 407 nm
  2. B. 414 nm
  3. C. 207 nm
  4. D. 103.5 nm

Answer

C. 207 nm

Step-by-step solution

Energy is, E = hc E = 1242 ~nm - eV = 1242 6 =207 ~nm
