People are trying to work out the best way to use waves to make electricity. Lots of experiments into wave energy are carried out at the European Marine Energy Centre on Orkney. Orkney is exposed ...

It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through, they can travel through a vacuum. Light from the Sun reaches Earth through the vacuum of space.

In others atoms the waves simply can't make the jump to the necessary location.) Work like this laid down the ground work for the research Bell Labs would do a decade later turning a semiconductor ...
