1. Refraction is the bending of a wave disturbance as it passes from one --------- into another

Unit used to measure the frequency

When the wave spreads out and goes through an opening or around corner

------------- is the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through.

They are waves that need a medium to travel through

The distance between two crests or two troughs
