Answer:

The answer is

$2.86 * {10}^( - 19) \: J$

Step-by-step explanation:

The energy of a quantum of light can be found by using the formula

where

E is the energy

f is the frequency

h is the Planck's constant which is

6.626 × 10-³⁴ Js

From the question

f = 4.31 × 10¹⁴ Hz

We have

E = 4.31 × 10¹⁴ × 6.626 × 10-³⁴

We have the final answer as

$2.86 * {10}^( - 19) \: J$
