The energy gap of silicon is 1.14 eV. Find the maximum wavelenth at which silicon starts energy absorption.
Text Solution
AI Generated Solution
To find the maximum wavelength at which silicon starts energy absorption, we can follow these steps:
### Step 1: Understand the given data
The energy gap (E) of silicon is given as 1.14 eV. We need to convert this energy into joules because the formula we will use requires energy in joules.
### Step 2: Convert energy from eV to joules
1 eV is equal to \(1.6 \times 10^{-19}\) joules. Therefore, we can convert 1.14 eV to joules:
