A p type semiconductor has acceptor level 30 mev above the valence band what will be the maximum wavelength of light that can create a hole

Explanation

To solve the problem of finding the maximum wavelength of light that can create a hole in a p-type semiconductor with an acceptor level of 30 meV above the valence band, we can follow these steps:

### Step 1: Understand the Energy Requirement
The energy required to create a hole in the p-type semiconductor is given as 30 meV. This energy corresponds to the minimum energy needed for an electron to transition from the valence band to the acceptor level.

### Step 2: Convert Energy from MeV to Joules
To use the energy in calculations involving wavelength, we need to convert the energy from meV to joules. The conversion factor is:
1 eV = 1.6 × 10^-19 Joules.
