At an instant in time, the electric and magnetic fields of an electromagnetic wave are given by - -6.25 x 10-3 v/m and b = -2.08 x 10-111 . find the poynting vector for this wave. (express your answer in vector form.) w/m2 s =

Poynting vector,

Explanation:

It is given that, The electric and magnetic fields of an electromagnetic wave are given by :

Electric field,

Magnetic field,

We need to find the Poynting vector for this wave. the Poynting vector is given by :

So, the Poynting vector for this wave is . Hence, this is the required solution.

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

we need to know the time interval during which the force acts. impulse of force = momentum change
