The amplitude of the wave's electric field is times if the intensity of some electromagnetic wave doubles.
- What is electromagnetic wave:
Electromagnetic waves also called EM waves, are waves that are created as a result of vibrations between an electric field and magnetic field.
The formula of Intensity of electromagnetic wave:
- I = 1/2 ( c* ε(0)* E(0)^2 )
where c is speed of light
E is amplitude of electric field
here Intensity of EM waves doubles so,
I' = 2*I
we can say that,
I ∝ E^2
E = sqrt ( I )
E' = sqrt ( 2*I )
hence
E' = * E
so, the amplitude of the wave's electric field is times if the intensity of some electromagnetic wave doubles

The electromagnetic wave shown above is made up of vibrating Electric fields.
I assume this is why electromagnetic waves can travel through a vacuum, due to lack of matter.
Answer:
500 N
Explanation:
Natural bouyency will keep the diver in the same place, no matter what the mass of gfs. This means if the diver is displacing with a weight of 500 N, the upthrust will also be 500 N.
