Expert Answer

Step 1

Frequency and energy are related to each other directly.

Formula,

Energy = (Planck's constant x frequency)

 

Step 2

Given,

the threshold frequency for dislodging an electron from a zinc metal surface is = 8.54 x 10^14 Hz

Using the above formula we can calculate the minimum amount of energy required t...
