En la ionosfera se produce la reflexión de las

ondas de radio​

La parte ionizada de la atmósfera de la Tierra se conoce como ionosfera. La luz ultravioleta del sol choca con los átomos de esta región y suelta los electrones. ... Esto es lo que da nombre a la ionosfera y son los electrones libres los que provocan la reflexión y absorción de las ondas de radio.
