The angle made by electric field with the magnetic field in an electromagnetic wave is 90° or right angle.
<u>Explanation:</u>
The electrical & magnetic fields are at the 90 degree i.e at the right angles to the way the wave travels. The electric field oscillates back and forth in one plane while the magnetic field oscillates back and forth in a perpendicular plane;
the vibration, a transverse vibration, moves in a similar direction of each of the oscillating fields. All electromagnetic waves are created by accelerated charges, and the electromagnetic force follows the inverse-square law; the magnitude of the force declines as one above the squared source distance.
Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).
