Answer:

$E=2.85* 10^(-23)\ J$

Step-by-step explanation:

Given that,

The frequency of light,
$f=4.3* 10^(10)\ Hz$

We need to find the energy of light. The formula for the energy is given by :

E=hf Where h is Planck's constant

Putting all the values of h and f, we get :

$E=6.63* 10^(-34)* 4.3* 10^(10)\\\\E=2.85* 10^(-23)\ J$

So, the energy of light is
$2.85* 10^(-23)\ J$ .
