1. Regarding the true characteristics of electromagnetic waves, which of these is correct?

They are mechanical waves that need a material medium to travel

Their electric and magnetic components oscillate parallel to each other

They can travel through a vacuum, with electric and magnetic fields mutually perpendicular to each other

They can only travel through solids, never through empty space

Electromagnetic waves need no medium and can cross a vacuum. Their oscillating electric and magnetic fields are mutually perpendicular to each other and to the wave’s direction of travel.
