In 1905, Albert Einstein provided an explanation of the photoelectric effect – that various metals emit electrons when light is shined on them – by suggesting that a beam of light is not simply a wave ...

We are surrounded by waves. tiny vibrational waves transport sound to our ears. Light waves stimulate the retinas of our eyes. Electromagnetic waves bring radio, television and endless streaming ...

Ever since Democritus – a Greek philosopher who lived between the 5th and 4th century's BCE – argued that all of existence was made up of tiny indivisible atoms, scientists have been speculating as to ...

Adjunct Senior Research Fellow , School of Mathematical Sciences, Monash University It’s hard to imagine life without mobile phones, radio and television. Yet the discovery of the electromagnetic ...

Light waves might be able to drive future transistors. The electromagnetic waves of light oscillate approximately one million times in a billionth of a second, hence with petahertz frequencies. In ...

On August 17, after a journey taking 130 million years, the gravitational wave signal of two neutron stars, spiraling inwards in the final stages of a merger, finally arrived at Earth. As the surfaces ...

One of the landmark discoveries of 19 th century physics was the realisation that electricity, magnetism and light are all connected. Experiments had already shown that the movement of electrical ...
