Question

which of the following are electromagnetic waves?
□ ultraviolet light
□ microwaves
□ x-rays
□ seismic p waves
□ seismic surface waves
□ gamma rays
□ infrared
□ seismic s waves
□ radio waves
□ visible light

Explanation:

Electromagnetic waves are transverse waves that propagate through oscillating electric and magnetic fields, requiring no medium. They include the electromagnetic spectrum (radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, gamma rays). Seismic waves (P, S, surface) are mechanical waves needing a medium (earth's layers), so they are not electromagnetic.

Answer:

ultraviolet light, microwaves, x-rays, gamma rays, infrared, radio waves, visible light
