which light behaves called the “photoelectric
effect.” At the time, it was thought that light
always moved in continuous waves. Albert
believed that although this was true most of the
time, there were conditions under which light
changed instead into disconnected particles.
These particles would become known as photons,
which were never still, but always moving.
WHAT ARE WAVES?
In physics, a wave is what happens when energy moves
from one place to another. Waves happen around us every
day. An easy example of this is when a raindrop falls into
water. The energy that comes from the raindrop hitting
the water causes waves.
