At a given location in space, the magnetic field in an electromagnetic wave is increasing. How is the electric field changing at that same location?

a. The electric field is increasing.

b. The electric field is decreasing.

c. The electric field is not changing.

Option a) is correct

Explanation:

In the given question option a) (i. e the electric field is increasing) is correct.

The above option is correct because the electric field and the electromagnetic wave both are in the same phase of the EM wave. Thus, the electromagnetic wave and the electric field are directly proportional to each other.
