Answer:
The frequency is
Explanation:
From the question we are told that
The energy required to ionize boron is
Generally the ionization energy of boron pre atom is mathematically represented as
Here is the Avogadro's constant with value
So
=>
Generally the energy required to liberate one electron from an atom is equivalent to the ionization energy per atom and this mathematically represented as
=>
Here h is the Planks constant with value
So
=>
