Is light a wave or a particle?  Centuries old double silt experiment helps us shed light 😉 on this extremely old question.  Here the narrator in the video reexamines this test in modern society and starts off by asking a lot of common folk what they think light actually is.  You may be surprised to hear some of the answers if you are a science or physics person or maybe you’re not entirely sure yourself, or have just forgotten since physics class.  Rest assured, they get to the bottom of it in this clip and it’s really fun.  The original scientist was named Thomas Young.

Watch them in action and see what they find out in the video on the next page
