At any point through which two electromagnetic waves go, the net electric field

Question

At any point through which two electromagnetic waves go, the net electric field is

the difference between the respective electric field values in the two waves at that point.

the sum of the respective electric field values in the two waves at that point.

the difference between the respective electric field peak values in the two waves.

the sum of the respective electric field peak values in the two waves.

the difference between the respective electric field values in the two waves at that point.

the sum of the respective electric field values in the two waves at that point.

the difference between the respective electric field peak values in the two waves.

the sum of the respective electric field peak values in the two waves.

Explanation / Answer

The answer is B, the sum of the respective electric field values in the two waves at that point

Because the electric field is a vector quantity and the resultant is obtained by summing up the individual vectors,i.e. electric field.
