A difference of 2.3 eV separates two energy levels in an atom. What is the frequency of radiation emitted when the atom transits form the upper level to the lower level.

Explanation

To find the frequency of radiation emitted when an atom transitions from an upper energy level to a lower energy level, we can follow these steps:

### Step 1: Understand the Energy Difference
We are given the energy difference between two energy levels in an atom, which is 2.3 eV.

### Step 2: Convert Electron Volts to Joules
We need to convert the energy from electron volts (eV) to joules (J) because the formula we will use requires energy in joules. The conversion factor is:
1 eV = 1.6 × 10⁻¹⁹ J.
