1) Reflection is when a ray hits something reflective then bounces back. For example, light reflects off a mirror, which is why you can see yourself in a mirror.
2) Wavelength measures the size of a wave. It is measured from the crest or trough of one wave to the crest or trough of another.
3) Refraction occurs when waves go through different mediums at different speeds. This is why a straw looks bent when in water.
4) Frequency is a way of measuring the speed of a wave. It shows how many waves pass every unit of time.
5) Absorption means that all of the waves were absorbed into the medium and none of them passed through.
