Sir/mam I want to ask u that how exactly do electromagnetic waves travel in Vacuum. I know that changing electric and magnetic fields with time give rise to Each other,but please explain me how actually without any medium they travel. Bcoz if no material medium is present then how disturbances are carried in vacuum please clear this to me.
