Question

What oscillates in e.m. waves? Give two examples of e.m. waves.

Answer 1

Hint: An electromagnetic wave is defined as a wave created by an accelerated charge that propagates over space as coupled electric and magnetic fields oscillating perpendicular to one another and the wave's propagation direction. Electromagnetic waves have a transverse nature.

Complete step-by-step answer
We know that the word e.m. stands for electromagnetic waves. Electromagnetic waves oscillate the vectors of electric and magnetic fields. They swing back and forth perpendicular to each other and perpendicular to the propagation direction emissions of electromagnetic waves. Light waves, X-rays, gamma rays, infrared rays, and radio waves are all examples of electromagnetic waves.

Hence, electric and magnetic fields are oscillating in e.m. waves. The two examples of e.m. waves are Light waves, and radio waves

Additional information:In physics, Electrodynamics is the study of electromagnetic radiation and EM is the physical phenomenon associated with this idea. The properties of superposition apply to electric and magnetic fields. As a result, a field generated by a specific particle or a time-varying magnetic or electric field is donated to other fields in the same region. Furthermore, because magnetic and electric fields are vector fields, they combine according to vector addition.

Note: In a variety of ways, electromagnetic waves can be polarised, refracted, reflected, diffracted, or interfered with one another. In optics, for illustration, two or further coherent light waves may interact and produce an attendant irradiance that differs from the sum of the element irradiances of the individual light.
