1. Electromagnetic waves

are waves that have some electric and some magnetic properties. Changing electric and magnetic fields

2. electromagnetic radiation

energy that is transferred by electromagnetic waves

3. speed of an electromagnetic wave

300,000 kilometers per second

4. how does light act

light has many properties of a wave but can also act as a stream of particles

5. polarized light

light that has passed through a polarizing filter, only allowing waves moving in a certain direction to pass through

6. photoelectric effect

when light shines on an object and makes its electrons move to create electrical current
