Waves that travel through areas of compression and rarefaction are called:

• electrical waves

• diffracted waves

• longitudinal waves

Light is said to be refracted when it:

• is bent as it passes through matter

• bounces off a surface

• is taken into the matter and converted to heat energy

• is sent from one place to another
