Single photons are the smallest quantities of light and, despite having no mass, have many properties in common with particles. In fact, physicists often think of photons as particles -- particles that sometimes behave like waves. Physicists sometimes describe all particles as waves -- even those with mass, such as electrons and protons -- in order to better understand certain aspects of their behavior.

"It was first suggested in 1995 that the intense pressure waves, which can briefly exceed the speed of sound, could come from trombones."
