Artwork: How radio waves travel from a transmitter to a receiver. 1) Electrons rush up and down the transmitter, shooting out radio waves. 2) The radio waves travel through the air at the speed of light. 3) When the radio waves hit a receiver, they make electrons vibrate inside it, recreating the original signal.
A glass of port, a fortified wine. Fortified wine is a wine to which a distilled spirit, usually brandy, is added. Many different styles of fortified wine have been developed, including Port, Sherry, Madeira, Marsala, Commandaria wine, and the aromatized wine Vermouth.
Fortified wines are different from other spirits in that wines are made through the fermentation process and then fortified with alcohol whereas most spirits are the end result of certain processes of distillation.
