The three statements that are true about electromagnetic radiation are:

-Light is a kind of electromagnetic radiation.

-Electromagnetic radiation has no mass.

-Electromagnetic radiation can travel through a vacuum.

Explanation:

Electromagnetic radiation is a type of variable electromagnetic field, that is, a combination of oscillating electric and magnetic fields, which propagate through space, transporting energy from one place to another. From the classical point of view, electromagnetic radiation are the electromagnetic waves generated by the sources of the electromagnetic field and that propagate at the speed of light.

Electromagnetic radiation can be manifested in various ways such as radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays or gamma rays. Unlike other wave types, such as sound, which need a material medium to propagate, electromagnetic radiation can propagate through a vacuum.
