At the same speed (300 million m/s) 3 of 6 Which electromagnetic waves can be used for communication? Radio waves, microwaves, infrared and visible light 4 of 6 What properties do waves get as their wavelength gets shorter? They carry more information, they have a shorter range and they spread out less 5 of 6 What are optical fibres?
