Wave -particle duality is supported by...

• all of the above

What does particle- wave duality mean?

• Both Light and Matter have particle-like and wavelike properties at the same time

• Particles and waves both work on objects

An example of photoelectric effect in everyday objects is

• When you take photographs

• When you use a solar powered calculator

• When you turn on the heat

• When you turn a light bulb on

The photoelectric effect helped to explain how light was light a
