Find the de Broglie wavelength associated with an electron in a metal at `42^@C` of temperature . Take `m_e=9.11xx10^(-31)kg`.

Explanation

To find the de Broglie wavelength associated with an electron in a metal at a temperature of \(42^\circ C\), we will follow these steps:

### Step 1: Convert Temperature to Kelvin
First, we need to convert the temperature from Celsius to Kelvin. The formula for conversion is:
\[ T(K) = T(°C) + 273.15 \]
Substituting the given temperature:
