Answer:
The correct option is D
Step-by-step explanation:
From the question we are told that
The intensity of the first electromagnetic wave is
The amplitude of the electric field is

The intensity of the second electromagnetic wave is

Generally the an electromagnetic wave intensity is mathematically represented as

Looking at this equation we see that

=>
![(I_1)/(I_2) = [ ( E_(max)_1)/( E_(max)_2) ] ^2](https://img.qammunity.org/2021/formulas/physics/college/4pq0vuej8h9lff8zpl8e053pz4n6ldjk5u.png)
