Answer:
Option (1), (3) and (4) are correct.
Explanation:
When the oscillating electri and magnetic field interacts perpendicularly to each other, the electromagnetic radiations are produced. The electromagnetic radiations propagates in the perpendicular direction of both electric and magnetic field vectors.
For example, gamma rays, X rays, ultra violet rays, visible radiations, infrared rays, micro waves and radio waves.
Electromagnetic radiations do not require any medium for their propagation.
They do not carry mass, they carry energy only.
